2020-12-07(encore) Builder: use LazyLogging.logger.warn to print elaboration message ↵Jiuyang Liu
(#1670) * Builder: use LazyLogging.logger.warn to print elaboration message * add deprecation for chisel3.internal.ErrorLog.info. * add test to check elaboration message still exist. Co-authored-by: Kevin Laeufer <kevin.laeufer@sifive.com>
2020-12-01Fix RegInit of Bundle lits (#1688)Jack Koenig
Implemented by folding Element.ref into Data.ref. Element.ref had special handling for literals, but because Bundles can also be literals, there were code paths that tried to get the ref of a Bundle literal which was non-existent. Now, all literals are handled together. Because FIRRTL does not have support for Bundle literals, Bundle literal refs are implemented by materializing a Wire.

2020-11-11Ignore tests using System.setSecurityManager (#1661)Jack Koenig
The SecurityManager is global so is not thread-safe. This is the source of flaky tests in FIRRTL CI. Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2020-11-11Refine autonaming to have more intuitive behavior (#1660)Jack Koenig
* Refine autonaming to have more intuitive behavior Last name in an Expression wins, while the first Statement to name wins. This is done via checking the _id of HasIds during autonaming and only applying a name if the HasId was created in the scope of autonaming. There is no change to .autoSeed or .suggestName behavior. Behavior of chisel3-plugins from before this change is maintained. * Update docs with naming plugin changes
2020-11-05For HasId.setRef, have first set win (with force override) (#1655)Jack Koenig
This is a refinement of the assertion added in #1616 then removed in #1654. Because Records now set the refs of children upon binding, later, unbound Records could incorrectly override the refs. The first set should win.
2020-11-03Remove Data.setRef assertion (#1654)Jack Koenig
It causes issues for some legal (if awkward) patterns. A larger refactor of when refs are set could reinstate this check.

2020-10-30Fix bug where refs may not get set for Records (#1645)Jack Koenig
This requires a combination of things, but it happens to be a combination used by Diplomacy in Rocket Chip. It must be a Record in compatibility code with Vecs as fields and a mix of components with and without set directions.

2020-10-22Use Data refs for name prefixing with aggregate elements (#1616)Jack Koenig
* Use Data refs for name prefixing with aggregate elements Vecs set the refs of their elements upon construction of those elements. In the past, Records haven't set their elements refs until module close, but it can be done sooner. Doing it upon binding means that refs will at least be available for Records used in hardware elements. Since only bound Data can be connected to anyway, Aggregate elements being connected to will always have a ref which we can then use for creating naming prefixes. * Add tighter correctness checks * Handle more cases in connection prefixing Add support for forcing setRef to override a previous setting. This is only used by BlackBox ports which need to drop their io prefix. Also add a Try() around Data.bindingToString which sometimes throws exceptions when being used to .toString a Data in an error message. * Strip trailing spaces in names in compiler plugin

2020-10-19Change prefix stack to List[String] (#1617)Jack Koenig
This allows for sharing of the prefix stacks between Data, and removes a boxing per prefix stack element that is no longer necessary. Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2020-10-19Enable Cat of Zero Element Vec (#1623)Schuyler Eldridge
* Return 0.U for asUInt of a zero-element Seq Add a condition to SeqUtils.asUInt to have it return an unspecified width 0.U when applied to an empty sequence. This enables the ability to do a Cat of a zero-element sequence.

2020-10-14Provide user source locators in Builder.error errors (#1618)Jack Koenig
Package chisel3 was not properly marked as an internal package so source locators in reported errors would point to files like Bits.scala.
2020-10-13ExtModule's lacked support built in support for providing (#1154)Chick Markley
* ExtModule's lacked support built in support for providing the verilog source. This changes creates traits that can be used with ExtModule to provide the support currently found in BlackBox - Add support for ExtModule helpers - HasExtModuleResource to use addResource - HasExtModuleInline to use setInline - HasExtModulePath to use addPath - Add tests of the above support. - Note: These tests use Stage instead of Driver - Added ScalaDoc for HasBlackBoxInline#setInline * Fix the danged trailing commas. * Change to use `.transform` as the correct API for `ChiselStage`
2020-10-12When prefixing with a data, eagly get local name (#1614)Jack Koenig
Fixes #1606 Previously, the Data itself would be put on the prefix stack and its full name would be used as the prefix for subsequent names. This meant that prefixes would grow quadratically as the prefix is present both on the Data pushed to the stack, and on the stack itself. This is fixed by just using the "local" name of the Data being pushed on the stack. A related issue is deferring the name resolution. This led to unintuitive behavior when the name of a Data used as a prefix is overridden later (usually when the Data is a return value). The overriding name would show up in prefixes twice instead of once. It is much more intuitive to grab the name at the moment of the connection creating the prefix rather than deferring to later.

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.

2020-09-04Better Building of FIRRTL From Source (#1563)Jack Koenig
Using JVM system properties sbt.sourcemode and sbt.workspace, one can now easily build chisel3 with firrtl from source Example use: Assuming firrtl is cloned into the chisel3 root directory: $ sbt -Dsbt.sourcemode=true -Dsbt.workspace=$PWD Alternatively, one can set these properties in .sbtopts which can then be committed, enabling building from source by default

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>
