Problems solved by technology

[0002] Since burst transmission can be in various forms such as incremental bursts of unspecified length, incremental bursts of specified length, and loopback bursts; in many random verifications, it is very likely that the burst length is very long, and many When a master device sends this kind of burst transmission, it is also very likely that when a master device is performing a burst transmission, another master device sends a burst transmission to the same slave device, interrupting the transmission of the previous master device. At the moment of interruption, the previous transaction will be passed to the scoreboard; in this way, the scoreboard will obtain part of the information transmitted by the first master device, which will cause the comparison to fail

Embodiment Construction

[0047] In order to fully understand the technical content of the present invention, the technical solutions of the present invention will be further introduced and illustrated below in conjunction with specific examples, but not limited thereto.

[0048] like Figure 1 to Figure 3 The specific example shown, where, as Figure 1 to Figure 2 As shown, the present invention discloses a multi-device-based AHB burst transmission interruption verification method, comprising the following steps:

[0049] S1, the master device is triggered in parallel, and the master device sends out the transaction so that the slave device can receive the transaction;

[0050] S2, detecting the slave device type selected by the master device, and searching for the corresponding queue;

[0051] S3, judging whether there is an address accessed by the master device in the queue; if it exists, then enters S6, if not, then enters S4;

[0052] S4, judging whether the address accessed by the master devic...

Abstract

The invention relates to an AHB burst transmission interruption verification method based on multiple devices and a system thereof. The authentication method comprises the following steps: S1, triggering the master device in parallel, and sending the transmission out so as to enable the slave device to receive the transmission; S2, detecting the slave device type selected by the master device andsearching the corresponding queue; S3, judging whether the address accessed by the master device exists in the queue; S4, judging whether the address accessed by the master device and the address accessed by the slave device are the same; S5, pressing the transaction of the slave device into the queue of the corresponding slave device; S6, sending the out-of-stack transaction in the queue to the scoreboard for comparison, so as to obtain the comparison result; S7, providing feedback of a comparison result. The invention realizes that the transfer of any master device can pass through the comparison of the data and the control signal of each beat in the scoreboard with the interrupted transfer received by the slave device, and ensures the accuracy of the comparison of the scoreboard in theDUT of the multi-master device and the multi-slave device.

Description

technical field [0001] The invention relates to a method for pushing and popping a queue, more specifically, a multi-device-based AHB burst transmission interruption verification method and a system thereof. Background technique [0002] Since burst transmission can be in various forms such as incremental bursts of unspecified length, incremental bursts of specified length, and loopback bursts; in many random verifications, it is very likely that the burst length is very long, and many When a master device sends this kind of burst transmission, it is also very likely that when a master device is performing a burst transmission, another master device sends a burst transmission to the same slave device, interrupting the transmission of the previous master device. At the moment of interruption, the previous transaction will be passed to the scoreboard; in this way, the scoreboard will obtain part of the information transmitted by the first master device, which will cause the co...
