From 67b4ce06e07fde80d5ac11cad4d673c501bdd421 Mon Sep 17 00:00:00 2001 From: Dan Ravensloft Date: Mon, 22 Jul 2019 12:15:22 +0100 Subject: intel: Map M9K BRAM only on families that have it This regresses Cyclone V and Cyclone 10 substantially, but these numbers were artificial, targeting a BRAM that they did not contain. Amusingly, synth_intel still does better when synthesizing PicoSoC than Quartus when neither are inferring block RAM. --- techlibs/intel/synth_intel.cc | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'techlibs/intel/synth_intel.cc') diff --git a/techlibs/intel/synth_intel.cc b/techlibs/intel/synth_intel.cc index d7b089503..87d83f0db 100644 --- a/techlibs/intel/synth_intel.cc +++ b/techlibs/intel/synth_intel.cc @@ -187,8 +187,15 @@ struct SynthIntelPass : public ScriptPass { } if (!nobram && check_label("map_bram", "(skip if -nobram)")) { - run("memory_bram -rules +/intel/common/brams.txt"); - run("techmap -map +/intel/common/brams_map.v"); + if (family_opt == "cycloneiv" || + family_opt == "cycloneive" || + family_opt == "max10" || + help_mode) { + run("memory_bram -rules +/intel/common/brams_m9k.txt", "(if applicable for family)"); + run("techmap -map +/intel/common/brams_map_m9k.v", "(if applicable for family)"); + } else { + log_warning("BRAM mapping is not currently supported for %s.\n", family_opt.c_str()); + } } if (check_label("map_ffram")) { @@ -217,7 +224,7 @@ struct SynthIntelPass : public ScriptPass { if (check_label("map_cells")) { if (!noiopads) run("iopadmap -bits -outpad $__outpad I:O -inpad $__inpad O:I", "(unless -noiopads)"); - run(stringf("techmap -map +/intel/%s/cells_map.v", family_opt.c_str())); + run(stringf("techmap -map +/intel/%s/cells_map.v", family_opt.c_str())); run("dffinit -highlow -ff dffeas q power_up"); run("clean -purge"); -- cgit v1.2.3 From 49528ed3bd391c1ba3d50f2a904b6ffdb9d11250 Mon Sep 17 00:00:00 2001 From: Dan Ravensloft Date: Wed, 24 Jul 2019 10:38:15 +0100 Subject: intel: Make -noiopads the default --- techlibs/intel/synth_intel.cc | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'techlibs/intel/synth_intel.cc') diff --git a/techlibs/intel/synth_intel.cc b/techlibs/intel/synth_intel.cc index d7b089503..539ba379f 100644 --- a/techlibs/intel/synth_intel.cc +++ b/techlibs/intel/synth_intel.cc @@ -61,8 +61,8 @@ struct SynthIntelPass : public ScriptPass { log(" from label is synonymous to 'begin', and empty to label is\n"); log(" synonymous to the end of the command list.\n"); log("\n"); - log(" -noiopads\n"); - log(" do not use IO pad cells in output netlist\n"); + log(" -iopads\n"); + log(" use IO pad cells in output netlist\n"); log("\n"); log(" -nobram\n"); log(" do not use block RAM cells in output netlist\n"); @@ -79,7 +79,7 @@ struct SynthIntelPass : public ScriptPass { } string top_opt, family_opt, vout_file, blif_file; - bool retime, flatten, nobram, noiopads; + bool retime, flatten, nobram, iopads; void clear_flags() YS_OVERRIDE { @@ -90,7 +90,7 @@ struct SynthIntelPass : public ScriptPass { retime = false; flatten = true; nobram = false; - noiopads = false; + iopads = false; } void execute(std::vector args, RTLIL::Design *design) YS_OVERRIDE @@ -125,8 +125,8 @@ struct SynthIntelPass : public ScriptPass { run_to = args[argidx].substr(pos + 1); continue; } - if (args[argidx] == "-noiopads") { - noiopads = true; + if (args[argidx] == "-iopads") { + iopads = true; continue; } if (args[argidx] == "-nobram") { @@ -215,8 +215,8 @@ struct SynthIntelPass : public ScriptPass { } if (check_label("map_cells")) { - if (!noiopads) - run("iopadmap -bits -outpad $__outpad I:O -inpad $__inpad O:I", "(unless -noiopads)"); + if (iopads || help_mode) + run("iopadmap -bits -outpad $__outpad I:O -inpad $__inpad O:I", "(if -iopads)"); run(stringf("techmap -map +/intel/%s/cells_map.v", family_opt.c_str())); run("dffinit -highlow -ff dffeas q power_up"); -- cgit v1.2.3
