|\ | | | | coolrunner2: Improve optimization for TFF/counters
| * coolrunner2: Add an ANDTERM/XOR between chained FFsRobert Ou2018-03-311-0/+58
| | | | | | | | | | | | | | 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.
| * coolrunner2: Split multi-bit netsRobert Ou2018-03-311-0/+1
| | | | | | | | | | The PAR tool doesn't expect any "dangling" nets with no drivers nor sinks. By splitting the nets, clean removes them.

* First draft of Verilog parser support for specify blocks and parameters.Udi Finkelstein2018-03-273-2/+201
| | | | | 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
