build process for litex sim

very simple:

make run_sim

build process for ls180

for the variant without 4k srams:

cd soc
make ls180_verilog
cd src/soc/litex/florent
make ls180
cp ls180.il /tmp

at this point you can copy ls180.il over to the coriolis2 chroot, into soclayout experiments9:

soclayout/experiments9/non_generated/full_core_ls180.il 

and you can then begin the build process inside the coriolis2 chroot:

cd soclayout/experiments9
nohup ./build_full.sh &

note that you will need yosys checkout 049e3abf9 for the coriolis2 build this is encoded into the dev-env-setup script which automates the chroot creation https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD

build process for ls180 with 4k srams

for the variant with 4k srams:

cd soc
make ls180_4k_verilog
cd src/soc/litex/florent
make ls1804k
cp ls180.il /tmp

at this point you can copy ls180.il over to the coriolis2 chroot, into soclayout experiments9 in a different location from the above:

soclayout/experiments9/non_generated/full_core_4_4ksram_ls180.il 

and you can then begin the build process inside the coriolis2 chroot:

cd soclayout/experiments9
nohup ./build_full_4ksram.sh &

note that you will need yosys checkout 049e3abf9 for the coriolis2 build this is encoded into the dev-env-setup script which automates the chroot creation https://git.libre-soc.org/?p=dev-env-setup.git;a=blob;f=coriolis2-chroot;hb=HEAD
