|\ | | | | 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.
| * memory_bram: add `attr_icase` option.whitequark2020-02-061-7/+35
| | | | | | | | | | 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.

Part of fix for #1841.
