Zachary Snow aa35f24290 sv: auto add nosync to certain always_comb local vars 
If a local variable is always assigned before it is used, then adding
nosync prevents latches from being needlessly generated.

Zachary Snow e833c6a418 verilog: use derived module info to elaborate cell connections 
- Attempt to lookup a derived module if it potentially contains a port
  connection with elaboration ambiguities
- Mark the cell if module has not yet been derived
- This can be extended to implement automatic hierarchical port
  connections in a future change
 2021-10-25 18:25:50 -07:00

Zachary Snow d6fe6d4fb6 sv: support wand and wor of data types 
This enables the usage of declarations of wand or wor with a base type
of logic, integer, or a typename. Note that declarations of nets with
2-state base types is still permitted, in violation of the spec.

Updates for CHANGELOG (#2997) 
Added missing changes from git log and  group items
 2021-09-13 16:25:42 +02:00
Marcelina Kościelnicka fd79217763 Add v2 memory cells. 2021-08-11 13:34:10 +02:00
Marcelina Kościelnicka 19720b970d memory: Introduce $meminit_v2 cell, with EN input. 2021-07-28 23:18:38 +02:00
Marcelina Kościelnicka 9a4f420b4b Replace opt_rmdff with opt_dff. 2020-08-07 13:21:03 +02:00
Marcelina Kościelnicka dc07ae9677 techmap: Add _TECHMAP_CELLNAME_ special parameter. 
This parameter will resolve to the name of the cell being mapped.  The
first user of this parameter will be synth_intel_alm's Quartus output,
which requires a unique (and preferably descriptive) name passed as
a cell parameter for the memory cells.
 2020-07-21 15:00:54 +02:00

Eddie Hung a9ec0defb9 kernel: add design -delete option 2020-04-16 08:05:18 -07:00
Marcelina Kościelnicka 38a0c30d65 Get rid of dffsr2dff. 
This pass is a proper subset of opt_rmdff, which is called by opt, which
is called by every synth flow in the coarse part.  Thus, it never
actually does anything and can be safely removed.

Marcin Kościelnicki a235250403 xilinx: Add xilinx_dffopt pass (#1557) 2019-12-18 13:43:43 +01:00
Marcin Kościelnicki aff6ad1ce0 xilinx: Improve flip-flop handling. 
This adds support for infering more kinds of flip-flops:

- FFs with async set/reset and clock enable
- FFs with sync set/reset
- FFs with sync set/reset and clock enable

Some passes have been moved (and some added) in order for dff2dffs to
work correctly.

This gives us complete coverage of Virtex 6+ and Spartan 6 flip-flop
capabilities (though not latch capabilities).  Older FPGAs also support
having both a set and a reset input, which will be handled at a later
data.
