vcs make file error #60

Closed clare7 closed 7 years ago

clare7 commented 7 years ago

Hi when I tried to make for /lowrisc-chip/vcs I get the following errors:

Error-[IND] Identifier not declared .../lowrisc-chip/minion_subsystem/verilog/minion_soc.sv, 66 Identifier 'one_hot_rdata' has not been declared yet. If this error is not expected, please check if you have setdefault_nettype to none.`

any advice?

Suppprt for vcs is experimental. Try moving the declaration of one_hot_rdata and friends earlier in the file (before first use).

Alright noted! thanks

No they should not be commented out. VCS has a stricter interpretation of Verizon ordering of statements than Vivado, so you need to move the declarations that VCS complains about earlier in the file. I have a feeling this bug was already fixed on some branch, but you do not say what branch you are working on.

The function of the signals is to multiplex between the control and data signals of the different Minion peripherals.
