From: Marcelina Kościelnicka Date: Wed, 11 Aug 2021 12:14:45 +0000 (+0200) Subject: test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. X-Git-Tag: yosys-0.10~50 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b98376884e559330a0de191fadb098eadfe3fe0c;p=yosys.git test/arch/{ecp5,ice40}/memories.ys: Use read_verilog -defer. These parts keep rereading a Verilog module, then using chparam to test it with various parameter combinations. Since the default parameters are on the large side, this spends a lot of time needlessly elaborating the default parametrization that will then be discarded. Fix it with -deref and manual hierarchy call. Shaves 30s off the test time on my machine. --- diff --git a/tests/arch/ecp5/memories.ys b/tests/arch/ecp5/memories.ys index 03de49cc0..44651ba25 100644 --- a/tests/arch/ecp5/memories.ys +++ b/tests/arch/ecp5/memories.ys @@ -1,197 +1,228 @@ # ================================ RAM ================================ # RAM bits <= 18K;
