In this example, RTL implemeted on the logik_demo eFPGA prints out a message when run in the Zero ASIC Digital Twin Platform. Each character in the message is sent as a UMI packet to the address 0x1000000. Packets received at this address are interpreted as characters to be printed by the emulator.
To get started, install Logik if you haven't already:
python -m pip install --upgrade logikThen build the bitstream with:
./umi_hello.py -remoteThis will take a couple of minutes, and resulting in a bitstream at build/umi_hello/job0/convert_bitstream/0/outputs/umi_hello.bin. Head over to the ZA Digital Twin Platform and follow the instructions there to simulate the bitstream.
To customize the message printed, edit the MESSAGE parameter in umi_hello.v, then run ./umi_hello.py again.
