From 930bcf0e75f3b8d6c5afbdffda5ef7fd7eddc964 Mon Sep 17 00:00:00 2001 From: Jannis Harder Date: Wed, 29 Jun 2022 18:28:34 +0200 Subject: [PATCH] smt2, btor: Revert calling memory_map -rom-only This approach had major issues with ROMs whose initialization was not fully defined. If required, memory_map -rom-only -keepdc should be called early in a formal flow instead. (This does require a careful choice of optimization passes though. Sby's scripts will be updated accordingly.) --- backends/btor/btor.cc | 1 - backends/smt2/smt2.cc | 1 - 2 files changed, 2 deletions(-) diff --git a/backends/btor/btor.cc b/backends/btor/btor.cc index 2dc3b5954..831a3ada2 100644 --- a/backends/btor/btor.cc +++ b/backends/btor/btor.cc @@ -1405,7 +1405,6 @@ struct BtorBackend : public Backend { log_header(design, "Executing BTOR backend.\n"); log_push(); - Pass::call(design, "memory_map -rom-only -keepdc"); Pass::call(design, "bmuxmap"); Pass::call(design, "demuxmap"); log_pop(); diff --git a/backends/smt2/smt2.cc b/backends/smt2/smt2.cc index c75d4a98a..7481e0510 100644 --- a/backends/smt2/smt2.cc +++ b/backends/smt2/smt2.cc @@ -1609,7 +1609,6 @@ struct Smt2Backend : public Backend { log_header(design, "Executing SMT2 backend.\n"); log_push(); - Pass::call(design, "memory_map -rom-only -keepdc"); Pass::call(design, "bmuxmap"); Pass::call(design, "demuxmap"); log_pop();
