2. Extract in nvc/test (i.e. over the top of this directory)
3. Install csh on your computer
4. Change "acc" in cfiles/*.mkf to "gcc". With GNU sed you can do
     sed -i'' s/acc/gcc/g cfiles/*.mkf
5. Set the VI_TEST environment variable to the vi_suite directory
     export VI_TEST=$(pwd)
6. Add $VI_TEST to your PATH 
     export PATH=$PATH:$VI_TEST
7. Patch the install script to support NVC
     patch -p0 < install.patch
8. Run ./install 
9. Run ./tcp
10. At the TCP# prompt:
     set branch on all
     set entorcfg entity
     execute
