From ec2f8796bd7a5180f257a92d7ffb2029571cada6 Mon Sep 17 00:00:00 2001 From: rockybulwinkle Date: Thu, 23 Jun 2022 13:34:08 -0500 Subject: [PATCH 1/2] Update tcl doc, yosys does not return data to tcl This pull request is to address YosysHQ/yosys#2980. The documentation, as originally written, does not make it clear that yosys commands, when used within a tcl script, do not return any value to the tcl script. This pull request notes this and offers a workaround via tee as noted in the issue. --- kernel/yosys.cc | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/kernel/yosys.cc b/kernel/yosys.cc index 64d2b4def..521717ce7 100644 --- a/kernel/yosys.cc +++ b/kernel/yosys.cc @@ -773,6 +773,12 @@ struct TclPass : public Pass { log("\n"); log("If any arguments are specified, these arguments are provided to the script via\n"); log("the standard $argc and $argv variables.\n"); + log("\n"); + log("Note, tcl will not recieve the output of any yosys command.
