Don't bother using the Xilinx simulator... Its buggy and extraordinarily slow.
|
|
As observed in v2023.2:
|
|
- clocking block assignments do not seem to actually simulate correctly.
|
|
assignment statements get ignored or the values get mangled.
|
|
- Streaming operators have all sorts of limitations.
|
|
|
|
Keeping this here in case someday it works better...
