| We wonder whether TritonRoute support all design rules in ISPD 2014/2015 tech files (https://www.ispd.cc/contests/14/web/benchmarks.html)? Example design rules are as follows:
|
|
|
| 1. PROPERTY LEF57_MINSTEP "MINSTEP 0.100 MAXEDGES 1 ;" ;
|
| 2. MINIMUMCUT 2 WIDTH 0.400 ;
|
| 3. MINENCLOSEDAREA 0.30 ;
|
| 4. PROPERTY LEF57_SPACING "SPACING 0.13 PARALLELOVERLAP ;”;
|
|
|
|
|

| We test with ispd 18&19 but not those. 2 is only relevant for pdn and I know we support 3. @osamahammad21 would you check on 1 & 4 |
|

| We currently parse for LEF58 rules. We don't parse LEF57 (by looking at /src/odb/src/lefin/lefin.cpp and /src/drt/src/io/io.cpp).
|
| I will start a PR for parsing LEF57.
|
|
|
| Also, we don't support PARALLELOVERLAP option for LEF58_SPACING in drt according to io.cpp:
|
|
|
| ```
|
| case odb::dbTechLayerCutSpacingRule::CutSpacingType::PARALLELOVERLAP:
|
| logger_->warn(utl::DRT,
|
| 260,
|
| "Unsupported LEF58_SPACING rule for layer {} of type "
|
| "PARALLELOVERLAP.",
|
| layer->getName());
|
| break;
|
| ```
|
|
|
| We support MAXEDGES for LEF58_MINSTEP as in io.cpp:
|
|
|
| ```
|
| for (auto rule : layer->getTechLayerMinStepRules()) {
|
| auto con = make_unique<frLef58MinStepConstraint>();
|
| con->setMinStepLength(rule->getMinStepLength());
|
| con->setMaxEdges(rule->isMaxEdgesValid() ? rule->getMaxEdges() : -1);
|
| con->setMinAdjacentLength(
|
| rule->isMinAdjLength1Valid() ? rule->getMinAdjLength1() : -1);
|
| con->setEolWidth(rule->isNoBetweenEol() ? rule->getEolWidth() : -1);
|
| tmpLayer->addLef58MinStepConstraint(con.get());
|
| tech_->addUConstraint(std::move(con));
|
| }
|
| ``` |
| |
| ### maliberty |
| We could add support for new rules if there is strong interest |
|
|
| ### refaay |
| Hi @liangrj2014 , we added support for PROPERTY LEF57_MINSTEP & PROPERTY LEF57_SPACING.
|
| Also, support for PARALLELOVERLAP will be added soon. |
|
|
| ### refaay |
| @liangrj2014 PARALLELOVERLAP is now supported for LEF57_SPACING &LEF58_SPACING properties. |
