From cf606998847a286a52f01d748372df396b59dd2b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marcelina=20Ko=C5=9Bcielnicka?= Date: Wed, 22 Jul 2020 13:34:11 +0200 Subject: synth_ice40: Use opt_dff. The main part is converting ice40_dsp to recognize the new FF types created in opt_dff instead of trying to recognize the mux patterns on its own. The fsm call has been moved upwards because the passes cannot deal with $dffe/$sdff*, and other optimizations don't help it much anyway. --- tests/arch/ice40/fsm.ys | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tests') diff --git a/tests/arch/ice40/fsm.ys b/tests/arch/ice40/fsm.ys index 223ba070e..e3b746202 100644 --- a/tests/arch/ice40/fsm.ys +++ b/tests/arch/ice40/fsm.ys @@ -12,5 +12,5 @@ cd fsm # Constrain all select calls below inside the top module select -assert-count 4 t:SB_DFF select -assert-count 2 t:SB_DFFESR -select -assert-count 15 t:SB_LUT4 +select -assert-max 15 t:SB_LUT4 select -assert-none t:SB_DFFESR t:SB_DFF t:SB_LUT4 %% t:* %D -- cgit v1.2.3
