MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit: * renames all remaining instances of "DRAM" (which is ambiguous) to "LUTRAM" (which is not), finishing the work started in the commit 698ab9be; * renames memory rule files to brams.txt/lutrams.txt; * adds/renames script labels map_bram/map_lutram; * extracts where necessary script labels map_ffram and map_gates; * adds where necessary options -nobram/-nolutram. The end result is that BRAM/LUTRAM/FFRAM aspects of every target are now consistent with each other. Per architecture: * anlogic: rename drams.txt→lutrams.txt, add -nolutram, add :map_lutram, :map_ffram, :map_gates * ecp5: rename bram.txt→brams.txt, lutram.txt→lutrams.txt * efinix: rename bram.txt→brams.txt, add -nobram, add :map_ffram, :map_gates * gowin: rename bram.txt→brams.txt, dram.txt→lutrams.txt, rename -nodram→-nolutram (-nodram still recognized), rename :bram→:map_bram, :dram→:map_lutram, add :map_ffram, :map_gates --- techlibs/ecp5/synth_ecp5.cc | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'techlibs/ecp5/synth_ecp5.cc') diff --git a/techlibs/ecp5/synth_ecp5.cc b/techlibs/ecp5/synth_ecp5.cc index a0ea6d1f9..3985da57a 100644 --- a/techlibs/ecp5/synth_ecp5.cc +++ b/techlibs/ecp5/synth_ecp5.cc @@ -266,13 +266,13 @@ struct SynthEcp5Pass : public ScriptPass if (!nobram && check_label("map_bram", "(skip if -nobram)")) { - run("memory_bram -rules +/ecp5/bram.txt"); + run("memory_bram -rules +/ecp5/brams.txt"); run("techmap -map +/ecp5/brams_map.v"); } if (!nolutram && check_label("map_lutram", "(skip if -nolutram)")) { - run("memory_bram -rules +/ecp5/lutram.txt"); + run("memory_bram -rules +/ecp5/lutrams.txt"); run("techmap -map +/ecp5/lutrams_map.v"); } -- cgit v1.2.3
