| | | | | | | | | | | | | | | | | | | | | | | | 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
| * | Add FuseSoC .core file for picosocOlof Kindgren2018-07-271-0/+23
| | | | | | | | | | | | | | | This allows other cores to depend on the generic parts of picosoc and use that as a base design.

|/ / | | | | | | | | | | | | | | | | | | 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

| * | Bypass picosoc compile order check if PICORV32_REGS is defined.Olof Kindgren2018-05-181-0/+2
|/ / | | | | | | | | | | | | | | | | | | | | | | | | 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
