13 paź 2023 · This tool generates VHDL, Verilog or MyHDL code for use in FPGAs to calculate CRC (Cyclic Redundancy Check) checksums. The generated HDL code is synthesizable and combinatorial. That means the calculation runs in one clock cycle on an FPGA.
This code generator creates HDL code (VHDL, Verilog or MyHDL) for any CRC algorithm. The HDL code is synthesizable and combinatorial. That means the calculation runs in one clock cycle on an FPGA.
24 sty 2017 · This snippet writes the correct CRC for Ethernet. Python 3 # write payload for byte in data: f.write(f'{byte:02X}\n') # write FCS crc = zlib.crc32(data) for i in range(4): byte = (crc >> (8*i)) & 0xFF f.write(f'{byte:02X}\n') Python 2
Universal CRC generator module. Following module can generate any CRC up to CRC64 with any polynomial. The idea is that logic synthesizer will (should) optimize nested for loops into minimal amount of XOR gates. Synthesis optimizations were tested in Quartus Prime 17.1 Lite and Vivado 2018.2.
