For å kjøre Cocotb (etter installasjon - )

Om cocotb

Cocotb sørger for at vi linker simulator (her: GHDL eller Questa) med python. Under simulering kjøres vekselvis simulator eller python fil- de kjører ikke samtidig. De triggerne (await..) vi bruker i python testbenken bestemmer når simulatoren overlater roret til python koden. Etter simuleringen er ferdig så ramser cocotb opp kjøreresultatet.

Kjøre cocotb

• I folderen med makefile, kjør

make

Makefil

Makefila sørger for kompilering og kjøring av Cocotb, samt evt kjøring av GUI eller lagring av waveform fil

• tb_<modulnavn>.py må inneholde python-testbenken

• Makefile for GHDL

# Makefile for GHDL
# defaults
SIM ?= ghdl
TOPLEVEL_LANG ?= vhdl
# VHDL 2008
EXTRA_ARGS +=--std=08
# TOPLEVEL is the name of the toplevel module in your VHDL file
TOPLEVEL = first
VHDL_SOURCES += $(PWD)/../lab1/$(TOPLEVEL).vhd
#VHDL_SOURCES += $(PWD)/../../hdl/*.vhdl
SIM_ARGS +=--wave=$(TOPLEVEL).ghw
# MODULE is the basename of the Python test file
MODULE = tb_$(TOPLEVEL)
# include cocotb's make rules to take care of the simulator setup
include $(shell cocotb-config --makefiles)/Makefile.sim
# removing generated binary of top entity and .o-file on make clean
clean::
-@rm -f $(TOPLEVEL)
-@rm -f e~$(TOPLEVEL).o

• Makefile for Questa
  • MERK: Dette oppretter folderen /sim_build/
    • Hvis den finnes fra før kan det gi problemer
    • /sim_build/ kan trygt slettes
