According to the data comparison requirements of input excitation and output response of "power generation core", a comprehensive verilog code is written. The design of the code is completely in accordance with the timing requirements of the "power generation core".

According to the design idea of building a test platform based on programmable devices, the method of building a functional test platform is as follows: using programmable logic devices to generate input excitation and process output response; ROM is used to store DSP core program, control register parameters, pulse compression coefficient and filter coefficient. SRAM is used as an off-chip cache.

2. Hardware implementation

According to the realization block diagram of the functional test platform, the schematic diagram and PCB design are carried out, and finally a system platform for functional test of "power core" is designed.

Classification of programmable logic devices;

1. The circuits in fixed logic devices are permanent, and they perform a function or a set of functions-once manufactured, they cannot be changed.

2. Programmable logic device (PLD) is a standard finished component, which can provide customers with a wide range of logic capabilities, characteristics, speed and voltage characteristics-and this device can be changed at any time, thus completing many different functions.
