From 38a0c30d65584335fee3e17f9075711853638ac3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marcelina=20Ko=C5=9Bcielnicka?= Date: Sat, 11 Apr 2020 18:36:51 +0200 Subject: 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. --- techlibs/xilinx/synth_xilinx.cc | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'techlibs/xilinx') diff --git a/techlibs/xilinx/synth_xilinx.cc b/techlibs/xilinx/synth_xilinx.cc index ac4f5bcf4..1c190d37e 100644 --- a/techlibs/xilinx/synth_xilinx.cc +++ b/techlibs/xilinx/synth_xilinx.cc @@ -522,10 +522,9 @@ struct SynthXilinxPass : public ScriptPass } if (check_label("map_ffram")) { - // Required for dffsr2dff to work. + // Required for dff2dffs to work. run("simplemap t:$dff t:$adff t:$mux"); // Needs to be done before opt -mux_bool happens. - run("dffsr2dff"); if (help_mode) run("dff2dffs [-match-init]", "(-match-init for xc6s only)"); else if (family == "xc6s") -- cgit v1.2.3
