2021-06-10Stop Emitting BlackBoxResourceAnno (#1954)Schuyler Eldridge
* Change HasBlackBoxResource to Resolve Resources Change HasBlackBoxResource to resolve resources immediately and emit BlackBoxInlineAnno instead of a BlackBoxResourceAnno. This removes the need for a FIRRTL compiler to grok the Java Resource API in order to handle BlackBoxResourceAnno. Emit BlackBoxInlineAnno from HasExtModuleResource instead of BlackBoxResourceAnno.

2021-05-09Fix ShiftRegister with 0 delay. (#1903)Jiuyang Liu
* Add test to check ShiftRegister(s) with delay is 0. This should break ShiftRegister(x, 0) since last is not exist in a empty Seq. Originally, test only test 1 to 4, which missed a potential bug from #1723. * Fix ShiftRegister with 0 delay. if ShiftRegisters is empty, java will complain: ``` java.util.NoSuchElementException scala.collection.LinearSeqOptimized.last(LinearSeqOptimized.scala:150) ``` This fix this issue and return `in` directly when ShiftRegister size is 0.

2021-02-11Fix stack trace trimming across Driver/ChiselStage (#1771)Schuyler Eldridge
* Handle MemTypeBinding in Analog Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com> * Fix stack trace trimming across ChiselStage Fix bug in stack trace trimming behavior. Now, the following is what happens: 1. The Builder, if catching accumulated errors, will now throw a ChiselException with a Scala-trimmed Stack trace. Previously, this would throw the full excpetion. 2. The Elaborate phase handles stack trace trimming. By default, any Throwable thrown during elaboration will have its stack trace *mutably* trimmed and is rethrown. A logger.error is printed stating that there was an error during elaboration and how the user can turn on the full stack trace. If the --full-stacktrace option is on, then the Throwable is not caught and only the first logger.error (saying that elaboration failed) will be printed. 3. ChiselStage (the class), ChiselStage$ (the object), and ChiselMain all inherit the behavior of (2). Mutable stack trace trimming behavior is moved into an implicit class (previously this was defined on ChiselException only) so this can be applied to any Throwable. No StageErrors are now thrown anymore. However, StageErrors may still be caught by ChiselMain (since it is a StageMain). Testing is added for ChiselMain, ChiselStage, and ChiselStage$ to test all this behavior. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@sifive.com>

2021-01-21Remove val ioJack Koenig
Chisel projects no longer need -Xsource:2.11 when compiling with Scala 2.12. Autowrapping of "val io" for compatibility mode Modules is now implemented using reflection instead of calling the virtual method. Also move Chisel.BlackBox to new chisel3.internal.LegacyBlackBox

* ExtModule's lacked support built in support for providing the verilog source.

2020-09-09Add new annotation for Chisel Circuit serialization (#1580)Jack Koenig
ChiselCircuitAnnotation no longer extends CustomFileEmission, rather it is Unserializable. Also the --chisel-output-file is added to the ChiselCli. New phase AddSerializationAnnotations constructs a CircuitSerializationAnnotation from ChiselCircuitAnnotation and ChiselOutputFileAnnotation. Both .fir and .pb file formats are supported. Default format is .fir unless a --chisel-output-file is specified with a .pb extension.

2020-08-27Restore and deprecate Chisel.Driver (#1571)Jack Koenig
It shouldn't be removed until we also remove the underlying chisel3.Driver.
2020-08-26Add ChiselPhase, Stop writing files in ChiselStage$ methods, Expand ↵Schuyler Eldridge
ChiselStage$ helpers (#1566) * Add ChiselPhase * Use ChiselPhase in ChiselStage, remove targets Switch from a one-off PhaseManager inside ChiselStage to actually using the newly added ChiselPhase. This removes the targets method (and API) from ChiselStage. * Stop writing to files in ChiselStage$ methods Change the ChiselStage companion object methods, elaborate and convert, to not write files. Under the hood, these are switched from using ChiselStage (which, like all phases, will write files) to using ChiselPhase. * Test that ChiselStage$ methods write no files Modify existing ChiselStage object method tests to check that no files are written. * Expand ChiselStage$ API with more helpers This adds additional methods to the ChiselStage object for going directly from a Chisel module to a string including: CHIRRTL, high FIRRTL IR, Verilog, and SystemVerilog. Differing from their ChiselStage class counterparts, these take no arguments other than the module and write no files. * Add tests of new ChiselStage$ helper methods * Use ChiselStage object in tests Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
