Merge pull request #69 from olofk/picosoc_regs_v3 
Bypass picosoc compile order check if PICORV32_REGS is defined.
 2018-05-19 12:09:52 +02:00
Olof Kindgren 2ceb472178 Bypass picosoc compile order check if PICORV32_REGS is defined. 
Previously, picosoc.v needed to be sourced before picorv32.v to
ensure that the PICORV32_REGS `define (used to select implementation
for the register file) was set to picosoc_regs

This allows for overriding PICORV32_REGS, e.g. by setting it
externally in the EDA tool invocation. In this case, the compile
order between picorv32.v and picosoc.v is not important.

Note: This change will break the safety check if PICORV32_REGS
is defined between sourcing picorv32.v and picosoc.v

Small fixes to the IceStorm scripts

Austin Seipp 77a6b2dd26 scripts/icestorm: use 'yosys-config' to find data directory 
This fixes the icestorm script to query yosys-config itself for the
right data directory. Not only does this fix installs where yosys was
not installed into /usr/local, it also ensures Icarus picks up a data
directory consistent with the version of yosys that you're using.
