  • Simulate early and often; write testbenches alongside RTL.
  • Leverage synthesis-friendly coding patterns and adhere to timing constraints from the outset.
  • Plan for testability and power from the beginning — fixes late in physical design are costly.

If you want, I can:

  • Produce an expanded chapter-style PDF on any of the sections above,
  • Provide an RTL example (Verilog) for the simple pipeline datapath, or
  • Summarize key equations and timing diagrams for setup/hold and critical-path analysis.
