Description

TECHNICAL FIELD

[0001] The present application relates to the chip technical field, and particularly to a multi-channel communication method, device and equipment in network on chip (NOC) verification. BACKGROUND

[0002] The scoreboard in the network verification environment of the network on chip (NOC) is used to compare the transmission signals collected by the master port and the slave in the NOC network. In the verification process of the NOC network, the order of different transmissions between the path from each master to a slave is determined.

[0003] When the scoreboard is designed, the transmission order is random from the perspective of the path of multiple masters and slaves, because the arrival of each transmission data packet in the NOC network depends on the path and congestion of network transmission, and thus the arrival order of the transmission data is random and uncertain. The traditional verification method is to design a detection device for tracking the transmission data packet in the NOC network. However, if the above-mentioned order detection device is designed, the complexity of the verification environment is increased, and the execution efficiency of the verification environment is reduced.

[0026] Embodiment one

[0027] Figure 1 A multi-channel communication method flow chart in a network on chip NOC verification is provided for the first embodiment of the present application. The present embodiment can be applied to the case of multi-channel communication in a network on chip NOC verification. The method can be executed by a multi-channel communication device in a network on chip NOC verification. The device can be realized in the form of hardware and / or software. As shown in the figure, the method comprises: Figure 1

[0028] Step S101, respectively establishing independent sub-channel scoreboards between the master node and the slave node in the NOC.

[0029] ​Wherein, in each node of the NOC bus network, there are master nodes and slave nodes, each master can initiate transmission command and write data to each slave, and each slave returns response or read data to the master which initiates the command after receiving the command. The number of nodes in the NOC network is very large, for example, there are 64 nodes, each node includes 3 masters and 1 slave, so there are 192 masters and 64 slaves in total. According to the routing rules of the NOC network, the 192 masters can reach any one of the 64 slaves, and each slave needs to be able to send the response channel to the 192 masters.

[0030] Optionally, independent sub-channel scoreboards are respectively established between the master nodes and the slave nodes in the NOC, including: determining the communication paths of the master nodes and the slave nodes in the NOC; and establishing independent sub-channel scoreboards for each communication path.

[0031] Wherein, as Figure 2 The application scenario diagram of multi-channel communication in the NOC verification in the embodiment is shown in the figure. As described above, after determining all the masters and slaves contained in the NOC, the communication paths of the masters and the slaves are determined, and independent sub-channel scoreboards are established for each communication path.

[0032] In a specific implementation, since the verification of the NOC needs to be considered for the design of the scoreboards by decomposing into two channel types of request channel and response channel. For example, when the number of masters is 192 and the number of slaves is 64, for the request channel, there is an independent sub-channel scoreboard from each master to each slave, and the design is as follows:

[0033] master0->slave0, master0->slave1, master0->slave3,..., master0->slave63;

[0034] master1->slave0, master1->slave01, master1->slave03,..., master1->slave63; ......

[0036] master191->slave0, master191->slave1, master191->slave3,..., master191->slave63.

[0037] For the response channel, each slave-to-each master is an independent sub-channel score board, designed as follows:

[0038] slave0->master0, slave0->master1, slave0->master3,... slave0->master191;

[0039] slave1->master0, slave1->master1, slave1->master3,... slave1->master191; ...

[0041] slave63->master0, slave63->master1, slave63->master3,... slave63->master191.

[0042] Through the above operation, for different channel types, the master node master and the slave node slave are directly established independently of each other, respectively.

[0043] Step S102, when performing NOC verification, determine the channel type between the master node and the slave node.

[0044] Optionally, when performing NOC verification, the channel type between the master node and the slave node is determined, including: determining the initiator of communication when performing NOC verification; judging whether the initiator is the master node, if yes, determining the channel type as the request channel, otherwise, determining the channel type as the response channel.

[0045] Specifically, after creating an independent sub-channel score board between the master node and the slave node, before performing NOC verification and node communication, the channel type between the master node and the slave node needs to be determined, the channel type in the embodiment mainly includes the request channel and the response channel. The data initiation mode corresponding to different request channels is different, so the initiator of communication can be determined, when the initiator is the master node master, the channel type is determined as the request channel; when the initiator is the slave node slave, the channel type is determined as the response channel.

[0046] Among them, the request channel in the embodiment includes the read-write address channel and the write data channel, the response channel includes the read-write response channel and the read data channel, of course, the embodiment is only an example, and the channel types contained in the request channel and the response channel are not limited.

[0047] Step S103, according to the channel type, each master node and each slave node using sub-channel score board for communication.

[0048] Optionally, according to the channel type, each master node and each slave node using sub-channel score board for communication, comprising: when determining the channel type as request channel, transmitting the read-write address channel and the write data channel by the master node as the start point of data comparison of the sub-channel score board; receiving the read-write address channel and the write data channel by the slave node as the end point of data comparison of the sub-channel score board.

[0049] Optionally, according to the channel type, each master node and each slave node using sub-channel score board for communication, comprising: when determining the channel type as response channel, transmitting the read-write response channel and the read data channel by the slave node as the start point of data comparison of the sub-channel score board; receiving the read-write response channel and the read data channel by the master node as the end point of data comparison of the sub-channel score board.

[0050] In one implementation, for the request channel, the transmission is sequential from the perspective of one master, for example, the data transmitted by master 0 to slave 0 is M0A0 / M0A1 / M0A2 / M0A3, and the data received by slave 0 is M0A0 / M0A1 / M0A2 / M0A3, thus the data transmitted by the master is sequentially received at the slave side from the perspective of one master. From the perspective of multiple masters, when master 0 and master 1 simultaneously transmit data to slave 0 before the sub-channel scoreboard is established, the data transmitted by master 0 to slave 0 is M0A0 / M0A1 / M0A2 / M0A3, and the data transmitted by master 1 to slave 0 is M1A0 / M1A1 / M1A2 / M1A3 / M1A4, and since the order of receiving data at slave 0 is chaotic according to the design rules of the NOC bus network when master 0 and master 1 transmit data to slave 0, for example, the data received by slave 0 can be M0A0 / M0A1 / M1A0 / M0A2 / M1A1 / M0A3 / M1A2 / M1A3 / M1A4, thus the data order of master 0 and master 1 is chaotic. Therefore, if the conventional scoreboard design rules are used, an additional set of logic that is the same as the NOC bus design principle is required to record and predict the order of data packets in the verification environment, which obviously increases the complexity of the verification environment. In the present application, an independent sub-channel scoreboard is established to adapt to the design rules of the NOC bus network, thus when the independent first sub-channel scoreboard is established between master 0 and slave 0 for data transmission, the data transmitted by master 0 to slave 0 through the first sub-channel scoreboard is M0A0 / M0A1 / M0A2 / M0A3, and the data received by slave 0 through the first sub-channel scoreboard is still M0A0 / M0A1 / M0A2 / M0A3. Similarly, when the independent first sub-channel scoreboard is used for data transmission between master 0 and slave 0, the data transmitted by master 1 to slave 0 through the second sub-channel scoreboard is M1A0 / M1A1 / M1A2 / M1A3 / M1A4, and the data received by slave 0 through the second sub-channel scoreboard is still M1A0 / M1A1 / M1A2 / M1A3 / M1A4.Therefore, when master 0 and master 1 transmit data to slave 0 at the same time, since each of master 0 and master 1 communicates with the sub-channel score board established in advance and independent of slave 0, the data transmission of master 0 and master 1 is independent and does not interfere with each other, so that the accuracy of data transmission between nodes can be determined without additional detection device of data packet.

[0051] In the embodiment of the application, the independent sub-channel score board is established between the master node and the slave node of the NOC, the master node and the slave node can communicate based on the independent sub-channel score board, so that the determination of the transmission sequence between the master node and the slave node can be ensured without additional detection device, thereby reducing the complexity of the verification environment and improving the execution efficiency of the customer verification environment.

[0053] Figure 3 A flow chart of a multi-channel communication method in on-chip network (NOC) verification is provided in the embodiment two of the application, and the embodiment is based on the above-mentioned embodiment, and after the sub-channel score board is used for communication between each master node and each slave node according to the channel type, the communication result of the sub-channel score board is detected.

[0054] In step S201, the independent sub-channel score board is established between the master node and the slave node in the NOC.

[0055] Optionally, the independent sub-channel score board is established between the master node and the slave node in the NOC, including determining the communication path of each master node and slave node in the NOC, and establishing the independent sub-channel score board for each communication path.

[0056] In step S202, the channel type between the master node and the slave node is determined when the NOC verification is performed.

[0057] Optionally, the channel type between the master node and the slave node is determined when the NOC verification is performed, including determining the initiation end of communication when the NOC verification is performed, and judging whether the initiation end is the master node, if yes, determining that the channel type is the request channel, or if not, determining that the channel type is the response channel.

[0058] Optionally, the request channel includes the read-write address channel and the write data channel, and the response channel includes the read-write response channel and the read data channel.

[0059] In step S203, the sub-channel score board is used for communication between each master node and each slave node according to the channel type.

[0060] Optionally, the master nodes and the slave nodes communicate according to the channel type by using the sub-channel scoreboards, including: when it is determined that the channel type is a request channel, transmitting the read-write address channel and the write data channel by the master node as the start point of data comparison of the sub-channel scoreboard; and transmitting the read-write address channel and the write data channel by the slave node as the end point of data comparison of the sub-channel scoreboard.

[0061] Optionally, the master nodes and the slave nodes communicate according to the channel type by using the sub-channel scoreboards, including: when it is determined that the channel type is a response channel, transmitting the read-write response channel and the read data channel by the slave node as the start point of data comparison of the sub-channel scoreboard; and transmitting the read-write response channel and the read data channel by the master node as the end point of data comparison of the sub-channel scoreboard.

[0062] Step S204: detecting the communication result of the sub-channel scoreboard.

[0063] In the embodiment, after the master nodes and the slave nodes communicate according to the channel type by using the sub-channel scoreboards, the communication result of the sub-channel scoreboard is detected, that is, whether the out-of-order problem exists in the communication result is detected.

[0064] For example, when master0 and master1 transmit data to slave0 at the same time, the data transmitted by master0 to slave0 is M0A0 / M0A1 / M0A2 / M0A3, and the data transmitted by master1 to slave0 is M1A0 / M1A1 / M1A2 / M1A3 / M1A4. When the independent sub-channel scoreboards are established, if the data received by slave0 still has the following out-of-order result: M0A0 / M0A1 / M1A0 / M0A2 / M1A1 / M0A3 / M1A2 / M1A3 / M1A4, it indicates that the first sub-channel scoreboard established between master0 and slave0 or the second sub-channel scoreboard established between master1 and slave0 fails. When the above result occurs, an alarm is sent to prompt the user to repair the established sub-channel scoreboard, thereby further improving the execution efficiency of the verification environment.

[0065] The embodiment of the application establishes independent sub-channel scoreboards between the master nodes and the slave nodes of the NOC, and the master nodes and the slave nodes can communicate based on the independent sub-channel scoreboards, thereby ensuring the determinacy of the transmission order between the master nodes and the slave nodes without adding a detection device, thus reducing the complexity of the verification environment and improving the execution efficiency of the verification environment.
