coolrunner2: Improve optimization for TFF/counters
2018-03-31 13:31:01 +02:00
Robert Ou 14e49fb057 coolrunner2: Add an ANDTERM/XOR between chained FFs
In some cases (e.g. the low bits of counters) the design might end up
with a flip-flop whose input is directly driven by another flip-flop.
This isn't possible in the Coolrunner-II architecture, so add a single
AND term and XOR in this case.

Robert Ou cfa3753b89 coolrunner2: Split multi-bit nets
The PAR tool doesn't expect any "dangling" nets with no drivers nor
sinks. By splitting the nets, clean removes them.

Udi Finkelstein 6378e2cd46 First draft of Verilog parser support for specify blocks and parameters.
The only functionality of this code at the moment is to accept correct specify syntax and ignore it.
No part of the specify block is added to the AST
