[0002] Currently, Innosilicon's USB PHY daughter card uses the FMC interface to enable USB PHY debugging on FPGA platforms. Meanwhile, Synopsys' HAPS-100, an FPGA platform with significant advantages, is equipped with multiple HapsTrak 3 interfaces. Its excellent EDA ease of use and robust ecosystem significantly shorten the debugging cycle of interface-type IPs, leading to its widespread adoption in the industry.

[0003] However, in practical applications, the HAPS-100 platform uses a HapsTrak 3 connector, while Innosilicon's USB PHY daughter card uses an FMC connector.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0035] like Figures 1 to 2 The diagram shows a structural schematic of an adapter board for a USB PHY daughter card according to an embodiment of the present invention. In this embodiment, the adapter board 100 for the USB PHY daughter card is used to connect the USB PHY daughter card 200 and the HAPS prototype verification platform 300. The adapter board 100 includes:

[0036] Several HapsTrak 3 connectors 110 are used for connection to the HAPS prototype verification platform 300;

[0037] FMC connector 120 is used to connect to USB PHY daughter card 200;

[0038] The plurality of HapsTrak 3 connectors 110 are connected to the FMC connector 120.

[0039] The adapter board 100 in this embodiment can be used to connect the USB PHY daughter card 200 and the HAPS prototyping platform 300. Specifically, the adapter board 100 is provided with a plurality of HapsTrak 3 connectors 110, which are used to establish a connection with the HAPS prototyping platform 300. The adapter board 100 also provides an FMC connector 120, which is used to connect with the corresponding external device, the USB PHY daughter card 200.

[0040] The connections on the adapter board 100 are as follows: several HapsTrak connectors 110 are connected to the FMC connector 120. Furthermore, the adapter board 100 is connected to the HAPS prototype verification platform 300 via several HapsTrak 3 connectors 110; and the adapter board 100 is connected to the USB PHY daughter card 200 via the FMC connector 120.

[0041] This establishes the connection between the USB PHY daughter card 200 and the adapter board 100, as well as the connection between the HAPS prototyping platform 300 and the adapter board 100. Ultimately, the adapter board 100 connects the USB PHY daughter card 200 and the HAPS prototyping platform 300, enabling communication and data transmission between them. The design of the adapter board 100 provides a convenient and reliable connection solution for the application of the USB PHY daughter card 200 on the HAPS prototyping platform 300.

[0042] In one embodiment, the plurality of HapsTrak 3 connectors 110 are adapted to and connected to the HapsTrak interface 310 of the HAPS prototype verification platform 300.

[0043] In this embodiment, the HAPS prototype verification platform 300 is HAPS-100, an FPGA-based prototype verification system, particularly suitable for prototyping large-scale chip designs requiring FPGA expansion. HAPS-100 allows chip designers, software developers, and verification engineers to communicate across regions and job categories, resulting in greater scale, higher performance, higher debugging efficiency, and lower cost. The HAPS-100 platform includes multiple HapsTrak interfaces 310, which are HapsTrak 3 connectors; that is, the HAPS-100 platform includes multiple HapsTrak 3 connectors.

[0044] like Figure 2 As shown, in this embodiment, the adapter board 100 has four HapsTrak 3 connectors 110, and the spacing between the four HapsTrak 3 connectors is a fixed spacing, meaning that the spacing between adjacent HapsTrak 3 connectors is equal. To ensure the connection between the HapsTrak 3 connectors 110 on the adapter board 100 and the HapsTrak interface 310 of the HAPS prototype verification platform 300, the spacing between adjacent HapsTrak 3 connectors 110 on the adapter board 100 is equal to the spacing between adjacent HapsTrak interfaces 310 on the HAPS prototype verification platform 300, achieving structural adaptation. When the HAPS prototype verification platform 300 is HAPS-100, the spacing between adjacent HapsTrak 3 connectors 110 on the adapter board 100 is equal to the spacing between adjacent HapsTrak 3 connectors on the HAPS-100 platform, ensuring the stability of the connection between the adapter board and the HAPS-100 platform.

[0045] Furthermore, since the HAPS-100 platform includes multiple HapsTrak 3 connectors, the four HapsTrak 3 connectors on the adapter board 100 can be connected to any four adjacent HapsTrak 3 connectors on the HAPS-100 platform. This embodiment does not limit the specific connection method; it can be selected according to actual needs. For example, if the HAPS-100 platform has ten HapsTrak 3 connectors, the four HapsTrak 3 connectors on the adapter board 100 can be connected to any four adjacent HapsTrak 3 connectors among the ten HapsTrak 3 connectors on the HAPS-100 platform. This flexible connection method can meet different application scenarios and requirements.

[0046] In one embodiment, the FMC connector 120 is adapted to connect to the FMC interface 210 of the USB PHY daughter card 200.

[0047] In this embodiment, the USB PHY daughter card 200 is a USB PHY daughter card from Innosilicon. Innosilicon's USB PHY daughter card has an FMC interface, which is used to connect to the FPGA platform. However, in practical applications, FPGA platforms such as the common HAPS prototyping platform often do not have an FMC connector that matches the FMC interface of the USB PHY daughter card. This prevents the HAPS prototyping platform from directly connecting to the USB PHY daughter card.

[0048] To address the aforementioned issues, this embodiment designs an adapter board suitable for USB PHY daughter cards. An FMC connector 120 adapted to the FMC interface 210 of the USB PHY daughter card 200 is provided on the adapter board 100, thereby realizing the connection between the USB PHY daughter card and the HAPS prototype verification platform.

[0049] It is worth noting that the FMC connector 120 on the adapter board 100 is adapted to the FMC interface 210 of the USB PHY daughter card 200. This adaptation is not merely physical; it also allows the adapter to receive signals from the USB PHY daughter card 200 and transmit signals to it. For example, Innosilicon's USB PHY daughter card contains over one hundred single-ended signals. The adapter board designed in this embodiment can fully meet the signal requirements of Innosilicon's USB PHY daughter card, ensuring signal integrity and stability during transmission.

[0050] In one embodiment, the HapsTrak 3 connector 110 is connected to the clock channel of the FMC connector 120.

[0051] It should be noted that the HapsTrak 3 connector 110 on the adapter board is connected to the clock channel of the FMC connector 120, and the adapter board can be used to transmit clock signals. Specifically, on the adapter board, the HapsTrak 3 connector 110 is connected to the CLK[0:3] pins of the FMC connector 120. This connection method has high flexibility and compatibility, and can support two different signal transmission configurations: single-ended clock signals and differential clock signals. The adapter board in this embodiment can be adapted to Innosilicon's USBPHY daughter card, which uses a single-ended clock signal transmission method. This adapter board can ensure that its clock signal is transmitted stably and accurately. In addition, for boards that use differential clock pairs, this adapter board can also meet their requirements and achieve effective transmission of differential clock signals. This design significantly improves the versatility and practicality of the adapter board, enabling it to adapt to the clock signal transmission requirements of various types of boards.

[0052] In one embodiment, the HapsTrak 3 connector 110 is connected to the data channel of the FMC connector 120.

[0053] It should be noted that the data channel of the HapsTrak 3 connector 110 on the adapter board is connected to that of the FMC connector 120, and the adapter board can be used to transmit data signals. Specifically, the HA[0:23] signal, LA[0:33] signal, and HB[0:21] signal of the HapsTrak 3 connector 110 and the FMC connector 120 on the adapter board are interconnected to form a data transmission channel. This adapter board has data signal transmission function, and its connection method supports single-ended data signal transmission and differential data signal transmission. Since the number of data groups involved in the data transmission process is large, the user can arbitrarily select the signal to be used according to actual needs, and this embodiment does not impose any limitations.

[0054] Meanwhile, the HA[0:23], LA[0:33], and HB[0:21] signals of the HapsTrak 3 connector and the FMC connector on the adapter board are connected using differential signal routing, further enhancing the stability and reliability of data transmission. This design supports not only single-ended data transmission but also differential signal transmission, providing users with a wide range of data signal options, thereby improving the versatility and practicality of the adapter board.

[0055] In one embodiment, the plurality of HapsTrak 3 connectors are disposed on the bottom surface of the adapter plate.

[0056] In one embodiment, the FMC connector is disposed on the top surface of the adapter plate.

[0057] It should be noted that the adapter board has a bottom surface and a top surface. Several HapsTrak 3 connectors are located on the bottom surface of the adapter board, while the FMC connector is located on the top surface. This layout effectively optimizes the space utilization of the adapter board, allowing for a more compact and rational arrangement of the connectors within a limited space, reducing space waste. Furthermore, this layout facilitates the connection between the adapter board and the FPGA platform or related boards.

[0058] In one embodiment, the model number of the HapsTrak 3 connector is SEAM-20-020-L-08-1-AK-TR.

[0059] In one embodiment, the FMC connector is model number ASP-134486-01.

[0060] It should be noted that the adapter board for USB PHY daughter cards provided by this utility model exposes all the signals used by the FMC connector. That is, the adapter board can completely transmit all types of signals involved in the FMC connector, including data, control, clock, and other types, providing a foundation for subsequent connection and signal interaction with different types of boards. This adapter board not only meets the debugging requirements of Innosilicon USB PHY daughter cards but also adapts to other FMC-type interface boards that need to be debugged on the HAPS-100 platform. Different FMC-type interface boards may have different functions and signal requirements. The adapter board in this embodiment exposes all the signals, providing a signal channel for these boards to connect to the HAPS-100 platform, enabling these boards to be debugged on the HAPS-100 platform.

[0061] Furthermore, in practical applications, multiple adapter boards designed in this embodiment can be used simultaneously with multiple FMC interface daughter cards. For example, in a complex hardware debugging project, it may be necessary to debug multiple FMC interface daughter cards with different functions simultaneously. By using multiple adapter boards, each adapter board can independently connect to one FMC interface daughter card, and because the adapter boards use standard FMC connectors, the connection process between these daughter cards and the adapter boards is more convenient and efficient. In this way, multiple FMC interface daughter cards can be debugged simultaneously, greatly improving the debugging efficiency of FMC interface daughter boards and avoiding the cost of frequently designing daughter cards due to different interfaces.

[0062] Meanwhile, the adapter board has multiple connection methods on the HAPS-100 platform, and users can choose different methods to connect the adapter board to the HAPS-100 platform according to actual needs and hardware layout.

[0063] It is important to emphasize that the adapter board for USB PHY daughter cards provided by this invention, based on the interface between Innosilicon's USB PHY daughter card and the HAPS-100 platform, uses a HapsTrak 3 connector on the adapter board to achieve a stable connection with the HAPS-100 platform. Simultaneously, the adapter board also uses an FMC connector to connect with Innosilicon's USB PHY daughter card, thus enabling the connection between Innosilicon's USB PHY daughter card and the HAPS-100 platform and meeting the debugging requirements of Innosilicon's USB PHY daughter card. This invention also allows multiple adapter boards to be used with multiple FMC interface daughter cards simultaneously, improving the debugging efficiency of FMC interface daughter boards and effectively avoiding the cost loss of frequent daughter card design due to different interfaces. The adapter board of this invention offers multiple connection methods on the HAPS-100 platform, allowing users to freely choose the appropriate method to connect the adapter board to the HAPS-100 platform according to actual project needs and hardware layout, enhancing the versatility of the adapter board.

[0064] In summary, this utility model provides an adapter board for a USB PHY daughter card, used to connect the USB PHY daughter card and the HAPS prototyping platform, comprising: a plurality of HapsTrak 3 connectors for connecting to the HAPS prototyping platform; and an FMC connector for connecting to the USB PHY daughter card. The plurality of HapsTrak 3 connectors are connected to the FMC connector.

[0065] This invention, based on the interface between Innosilicon's USB PHY daughter card and the HAPS-100 platform, utilizes a HapsTrak 3 connector on the adapter board to achieve a stable connection with the HAPS-100 platform. Simultaneously, the adapter board also employs an FMC connector to connect with the Innosilicon USB PHY daughter card, thus enabling the connection between the Innosilicon USB PHY daughter card and the HAPS-100 platform and meeting the debugging requirements of the Innosilicon USB PHY daughter card.
