From f19556801137091fa79a6d79395985474527b72d Mon Sep 17 00:00:00 2001 From: mergify[bot] Date: Tue, 27 Sep 2022 19:36:39 +0000 Subject: Use Treadle (on pull requests only) to speed up CI (backport #2341) (#2748) * Support using Treadle for 'sbt test' Treadle will be used as the "defaultBackend" when the environment variable CHISEL3_CI_USE_TREADLE is set. The intent is to set this variable during CI for pre-merge CI (aka on pull requests). (cherry picked from commit 7d39b7bd2b6f38dac90fe25064744ffc0ada0fe4) * Use Treadle for CI on pull requests (cherry picked from commit 82660673e56a816e68fcc068e3e04e127f076faf) Co-authored-by: Jack Koenig --- src/test/scala/chiselTests/ChiselSpec.scala | 5 ++++- src/test/scala/chiselTests/Vec.scala | 4 ++-- 2 files changed, 6 insertions(+), 3 deletions(-) (limited to 'src') diff --git a/src/test/scala/chiselTests/ChiselSpec.scala b/src/test/scala/chiselTests/ChiselSpec.scala index 6f560b94..e00afcf6 100644 --- a/src/test/scala/chiselTests/ChiselSpec.scala +++ b/src/test/scala/chiselTests/ChiselSpec.scala @@ -38,7 +38,10 @@ trait ChiselRunners extends Assertions with BackendCompilationUtilities { annotations: AnnotationSeq = Seq() ): Boolean = { // Change this to enable Treadle as a backend - val defaultBackend = chisel3.testers.TesterDriver.defaultBackend + val defaultBackend = { + val useTreadle = sys.env.get("CHISEL3_CI_USE_TREADLE").isDefined + if (useTreadle) chisel3.testers.TreadleBackend else chisel3.testers.TesterDriver.defaultBackend + } val hasBackend = TestUtils.containsBackend(annotations) val annos: Seq[Annotation] = if (hasBackend) annotations else defaultBackend +: annotations TesterDriver.execute(() => t, additionalVResources, annos) diff --git a/src/test/scala/chiselTests/Vec.scala b/src/test/scala/chiselTests/Vec.scala index 02743187..4a871890 100644 --- a/src/test/scala/chiselTests/Vec.scala +++ b/src/test/scala/chiselTests/Vec.scala @@ -6,7 +6,7 @@ import org.scalacheck._ import chisel3._ import chisel3.stage.ChiselStage -import chisel3.testers.BasicTester +import chisel3.testers.{BasicTester, TesterDriver} import chisel3.util._ import org.scalacheck.Shrink import scala.annotation.tailrec @@ -456,7 +456,7 @@ class VecSpec extends ChiselPropSpec with Utils { } property("Infering widths on huge Vecs should not cause a stack overflow") { - assertTesterPasses { new HugeVecTester(10000) } + assertTesterPasses(new HugeVecTester(10000), annotations = TesterDriver.verilatorOnly) } property("A Reg of a Vec of a single 1 bit element should compile and work") { -- cgit v1.2.3
