Chip verification is an important part of the chip design process, which is used to verify whether the functions and performance of the chip meet the design requirements. The chip verification board is used for ADM706ARZ The schematic design of the hardware platform for chip verification is an important part of the verification board. This paper will introduce the schematic design of the multi-core processor multi input chip verification board based on VU440T.
1. System block diagram design:
First, we need to design the system block diagram of the chip verification board. The system block diagram includes the main functional modules and the connection relationship between them. For the multi-core processor multi input chip verification board based on VU440T, the main functional modules include FPGA chip, DDR3 memory, clock module, power module, Ethernet interface, etc. These modules need to be connected to each other to realize the chip verification function.
2. FPGA chip design:
FPGA chip is the core part of the chip verification board, which contains multiple programmable logic units and internal memory. When designing the schematic diagram, it is necessary to connect the FPGA chip with other functional modules. For example, connect the FPGA chip with the DDR3 memory to realize the data reading and writing operation; Connect the FPGA chip with the clock module to provide the clock signal to the FPGA chip; Connect the FPGA chip with the power module to provide power to the FPGA chip, etc.
3. DDR3 memory design:
DDR3 memory is a module used to store data, which provides large capacity and high-speed data storage capacity. When designing schematic diagram, it is necessary to connect DDR3 memory with FPGA chip. Usually, DDR3 controller is used to connect FPGA chip with DDR3 memory, and read and write data through data bus and control bus.
4. Clock module design:
The clock module is a module used to provide clock signals, which provides clock synchronization signals for each functional module of the chip verification board. When designing the schematic diagram, it is necessary to connect the clock module with FPGA chip and other modules. Generally, the clock generator is used to generate the clock signal, and the clock signal is distributed to each functional module through the clock distributor.
5. Power module design:
The power module is a module used to provide power to the chip verification board, which provides the required power supply voltage and current for each functional module. When designing the schematic diagram, it is necessary to connect the power module with each functional module. Generally, the regulated power module is used to generate stable power supply voltage, which is distributed to various functional modules through the power management module.
6. Ethernet interface design:
Ethernet interface is a module used to communicate with external computers. It transmits and receives data through Ethernet protocol. When designing the schematic diagram, it is necessary to connect the Ethernet interface with the FPGA chip. Usually, Ethernet transceivers are used to convert Ethernet signals into data formats that can be processed by FPGA chips, and data transmission and reception are realized through Ethernet protocol stack.
Summary:
The schematic design of multi-core processor multi input chip verification board based on VU440T includes system block diagram design, FPGA chip design, DDR3 memory design, clock module design, power module design and Ethernet interface design. These designs need to connect various functional modules to achieve the function of chip verification. When designing the schematic diagram, it is necessary to consider the connection relationship and data transmission mode between each module to ensure the normal operation of the chip verification board.
