Open source silicon - Z80?

Does anyone know the likely hood this project is actually going to work and be for sale in the next year or so?

Taking a quick read through some of it, I find there is a stark contrast/spectrum of "development levels".

On one end you have the fact they designed silicon at the gate level.  At the other end you have them using MicroPython to test it.  Extremely low level to extremely high level.

Thanks for the mention !

   I've heard someone say, that the Z-80 (and 6502) are about the last fully comprehendable unit.  Now things go more specialized.  I obtained a lot of my Z-80 training by way of
   'The Z-80 Manual's by Rodney Zak's.

   Plus the usual 8-bit numbers are easy, compared with memory segmented functions, as in the 68000 IC.

They did not:

"The implementation is based around Guy Hutchison's TV80 Verilog core."
