| 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. | |
