1. There are extra markdown symbols in some commands.
   e.g. ``./scripts/init-vlsi.sh asap7``.

2. In addition to make syn, for the ASAP7 example without memory compiler, maybe add explicit instr likemake syn MACROCOMPILER_MODE='--mode synflops', so the synthesis won't fail with the error hammer-vlsi/technology/asap7/sram-cache.json (No such file or directory). It is unclear if the env var MACROCOMPILER_MODE needs to be explicitly passed to make syn again after make buildfile

@harrisonliew @dpgrubb13 Could you guys look into this?

I have a fix for the first issue and am testing the second part to see if we need a change.
