So why would vlsi guys use text (e.g., verilog) to design a cpu, instead of
1. IMO, graphical representations work nicely for low-complexity, but not
productive for highly complex systems
2. It is less productive to manipulate a graphical representation
3. text can be manipulated by all your favorite tools, more open ecosystem, no
lockin, proprietary formats
