WebAug 5, 2024 · I think asynchronous FIFO actually internally uses gray code counter to pass the write/read address pointer across the two clock domains. You will have metastability issue if more than 1 bit is toggled in one clock domain, but no all the bits are captured by the other clock domain.

If the data written matches the data that is read then it means that the design is working fine. To check this, copy the following python code in text editor and save it as ‘async_test.py’. the ‘ftd2xx’ Python library.

WebJun 29, 2024 · Asynchronous FIFO : Asynchronous FIFO is needed whenever we want to transfer data between design blocks that are in different clock domains. The difference in clock domains makes writing and reading the FIFO tricky. If appropriate precautions are not taken then we could end up in a scenario where write into FIFO has not yet finished and … WebJan 28, 2024 · 2. I'm trying to figure out the corner cases for verifying a synchronous FIFO during hardware verification.
