Olof Kindgren 12274e9f8a Add FuseSoC .core file for hx8kdemo
The core file specifies targets for FPGA implementation (fusesoc
build hx8kdemo) and simulation (fusesoc run --tool=<tool>
--target=sim hx8kdemo --firmware=path/to/firmware.he).

Simulation has been tested successfully with icarus, modelsim and xsim

Olof Kindgren 80f128713d Add FuseSoC .core file for picosoc
This allows other cores to depend on the generic parts of picosoc
and use that as a base design.

Olof Kindgren 262da6444c Add FuseSoC .core file for SPI Flash model
This allows other cores to depend on spiflash. Can also be used to
run the spiflash testbench with

fusesoc run --tool=<tool> spiflash --firmware=path/to/firmware.hex

This has been tested with icarus, modelsim and xsim. Fails with isim
If --tool is left out, icarus will be used as default

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
