I've commited d35e748 which provides correct block netlist integration.

To integrate a block, asides from the layout you have to provide :

* A Verilog blackbox netlist ("machin.v") for Yosys.
* A VHDL hollow netlist ("machin.vbe") for blif2vst and Coriolis
  at large.

Concerning the use in symbolic mode, we would need a symbolic abstract
view of the SRAM block. This is not very complicated, but still needs
a modicum of time. And as it has a bit complex interface than the
I/O pads, I leave it to the initiative of Staf.

And to use the Coriolis in full compliance we should also add a diode
(dio_x0) to the symbolic library nsxlib.

The layout integration is not completed yet, but in good way.
