Interview With Anton Blanchard - Microwatt: a 64 bit OpenPOWER core, VHDL and OpenLane

I interviewed Anton Blanchard about his MPW1 application - a 64bit OpenPOWER core written in VHDL.

We talked about:

  • VHDL vs Verilog
  • FPGA vs ASIC
  • Problems they faced with such a big design
  • SRAM vs DFFRAM
  • Software vs Hardware mentality
  • Fixing bugs and contributing to OpenLane
