1. Set the environment variables
Following tools have been installed in ~vagrawal/cse502-tools/bin:
- verilator
- gtkwave
To use these tools, you need to set the environment variables - LD_LIBRARY_PATH and PATH
a) LD_LIBRARY_PATH as /usr/local/packages/mpc-1.0.1/lib:/usr/local/packages/mpfr-3.1.2/lib:/usr/local/packages/gmp-5.1.3/lib:/usr/local/packages/gcc-4.8.1/lib64:/usr/local/lib
For csh,
setenv LD_LIBRARY_PATH /usr/local/packages/mpc-1.0.1/lib:/usr/local/packages/mpfr-3.1.2/lib:/usr/local/packages/gmp-5.1.3/lib:/usr/local/packages/gcc-4.8.1/lib64:/usr/local/lib
For bash,
export LD_LIBRARY_PATH=/usr/local/packages/mpc-1.0.1/lib:/usr/local/packages/mpfr-3.1.2/lib:/usr/local/packages/gmp-5.1.3/lib:/usr/local/packages/gcc-4.8.1/lib64:/usr/local/lib
b) PATH as /home/stufs1/vagrawal/cse502-tools/bin:$PATH
For csh,
setenv PATH /home/stufs1/vagrawal/cse502-tools/bin:$PATH
For bash,
export PATH=/home/stufs1/vagrawal/cse502-tools/bin:$PATH
2. Building/Running the code
a) Following are the commands to build and run the code
make // build code
make run // run code
The result of running the code will be a 'trace.vcd' waveform file. You can view it using gtkwave (see instructions below).
b) To change the program binary which you are decoding
- Edit the following line in Makefile
RUNELF=$(PWD)/prog2
3. Viewing the trace.vcd waveform
You can login to the server using the -Y option. You can view waveforms using the following command:
gtkwave trace.vcd
