| | | | | | | | | | | | | | | | | | | | | | | | 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.

Also, make the existing const-carry detection for low bits more generic (now handles cases where both BI and CI are constant, but not equal to one another). Fixes #1912.

|\ \ | | | | | | ice40/ecp5: add support for both 1364.1 and Synplify/LSE RAM/ROM attributes
| * | memory_map: add -attr option, to respect inference attributes.whitequark2020-04-031-6/+113
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, memory_map (which is always a part of a synth script) would always pick up any $mem cell that was not processed by a preceding pass and lower it down to $dff/$mux cells. This is undesirable for two reasons: * If there is an explicit inference attribute set on a $mem cell, e.g. (* ram_block *), then it is arguably incorrect to map such a memory to $dff/$mux cells. * If memory_map tries to lower a memory that was intended to be mapped to a large BRAM, it often takes extraordinarily long time to finish, produces an extremely large log file, and outputs an unusable design. After this commit, properly invoked memory_map will not map any memory that has an explicit inference attribute specified, solving the first issue, and alleviating the second. The default behavior is not changed.

| | | | | | | | | | | | | | | Some vendor toolchains use case insensitive matching for values of attributes that control BRAM inference.

* | | [NFCI] Deduplicate builtin FF cell types listMarcelina Kościelnicka2020-04-093-73/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | A few passes included the same list of FF cell types. Make it a global const instead. The zinit pass also seems to include a list like that, but given that it seems to be completely broken at the time (see #1568 discussion), I'm going to pretend I didn't see that.
