To use the picoJava-II source distribution, you need to set the following environment variables first: (if your shell is csh, type the following commands, if you are using sh type: variable=value; export variable)
setenv PICOJAVAHOME directory where you untar the distribution
setenv PROJECT picoJava-II
setenv DSVHOME $PICOJAVAHOME/$PROJECT/tools
setenv CLASSPATH ${DSVHOME}:${DSVHOME}/class:.
setenv PATH $DSVHOME/bin:$PATH
If you plan on building the instruction-accurate simulator or the RTL model, you need to set the following variables:
setenv CC_NAME the name of your C compiler, eg. cc or gcc
setenv CC_FLAGS the optimization flags for the C compiler, eg. -O
If you plan on running RTL simulations using Cadence Verilog-XL, you must set the following variables:
setenv VERITOOLS_PATH path to the veritools directory
setenv VLOG_PATH path to Verilog directory, eg. $VERITOOLS_PATH/verilog
setenv VLOG_NAME pj2vlog
setenv VFILES_PATH $PICOJAVAHOME/$PROJECT/sim/env/vfiles
If you plan on running RTL simulations using Synopsys VCS, you need to make sure 'vcs' is on your path and you must set the following variable:
setenv VCS_NAME pj2vcs
If you plan on using the steam script to run tests, you must set the following variable:
setenv STEAM_PLUSARGS $PICOJAVAHOME/$PROJECT/sim/config
