2022-04-21Update json4s-native to 4.0.5 (#2519)Lucheng Zhang
2022-03-25Fix anno deserialization when class field is not first (#2501)Fabian Schuiki
Update `findTypeHints` to allow for the "class" field in JSON objects to appear anywhere in the object. This used to rely on the field being the very first in the object, which is easily violated when reading JSON data generated externally, since an object's order of fields is unspecified and can be arbitrarily scrambled. Fixes #2497.
2021-12-17Deprecate all mutable methods on RenameMap (#2444)Jack Koenig
* Add renamemap.MutableRenameMap which includes these methods without deprecation * Deprecate Stringly typed RenameMap APIs which were accidentally undeprecated a while ago Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
2021-11-12Let firrtl based applications run despite loading unknown annotations (#2387)Chick Markley
An application like barstools may contain a main that loads an annotations file containing annotation classes that are not on it's classpath. This change allows unknown annotations to be preserved by wrapping them in a UnrecognizedAnnotation. If annotations are then output to a file, they will be unwrapped during serialization This feature can be enabled via an AllowUnrecognizedAnnotations annotation Co-authored-by: chick <chick.markley@sifive.com> Co-authored-by: Jack Koenig <koenig@sifive.com>
2021-07-14Fix memory annotation deduplication (#2286)Jared Barocsi
* Add transform to deduplicate memory annotations * Add annotation deduplication to Dedup stage * ResolveAnnotationPaths and EliminateTargetPaths now invalidate the dedup annotations transform * Verilog emitter now throws exception when memory annotations fail to dedup Co-authored-by: Jack Koenig <koenig@sifive.com>
2021-06-15make PresetRegAnnotation public (#2254)Kevin Laeufer
* make PresetRegAnnotation public this annotation is useful outside the firrtl compiler: - to implement a pass that creates registers which need to be initialized at the beginning of simulation (e.g., for formal verification) - to support preset registers in treadle * add PresetRegAnnotation test and deal with annotation correctly in RemoveReset pass

2020-08-13Cleanup Named Targets (#1311)Schuyler Eldridge
* Add CleanupNamedTargets Transform Adds a new transform, CleanupNamedTargets, that will convert ReferenceTargets to InstanceTargets if any ReferenceTargets are found to be actually pointing at instances. This fixes an issue where a ComponentName pointing at an instance will be converted to a ReferenceTarget. Later on, this ReferenceTarget will not be properly renamed by other transforms, e.g., EliminateTargetPaths.

2020-06-22Support Memory Initialization for Simulation and FPGA Flows (#1645)Kevin Laeufer
* Support Memory Initialization for Simulation and FPGA Flows This adds a minimal annotation that allows users to influence if memories are randomly initialized, if all entries are initialized to the same scalar or if each entry should be initialized to a different value. We use the init block in order to initialize memories which is supported by verilator as well as yosys and has previously been used to randomize the initial memory contents. * LowerTypes: error when trying to split up a memory with MemoryInitAnnotation Currently the MemoryInitAnnotation only works for ground-type memories. We catch misuse of this annotation at the point of the firrtl compiler at which memories on non-ground type get split up, i.e., the LowerTypes transform. Chisel should try to prevent annotating non-ground type memories in the frontend, but it is nice to have an additional check. * MemoryInitSpec: test JSON deserialization * MemoryInitAnnotation: split up into three different annotations instead of exposing MemoryInitValue Co-authored-by: Albert Magyar <albert.magyar@gmail.com> Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>

2020-05-26Remove trivially dead code from now-redundant WIR/IR match patternsAlbert Magyar
2020-05-26[API change] Absorb repetitive WIR nodes into IRAlbert Magyar
* Absorb WRef into Reference * Absorb WSubField into SubField * Absorb WSubIndex into SubIndex * Absorb WSubAccess into SubAccess * Absorb WDefInstance into DefInstance ------------------------- API CHANGE SEVERITY -------------------------- This is projected to not break source-level compatibility with any known user code. However, it will break *binary* compatibility with all existing user FIRRTL passes, as is generally allowed with major releases of FIRRTL. --------------------------- DESCRIPTION -------------------------------- Previously, there were several nodes in WIR.scala that had a one-to-one correspondance with existing nodes in the standard firrtl.ir hierarchy. These nodes would have a case class resembling the corresponding standard IR node, but with the addition of one or more "analysis" fields. Since these fields (such as kind) represent helpful info that can be invalidated or set to Unknown (e.g. UnknownKind for Kind), it does not cause any issues to simply include these fields on any in-memory representation of FIRRTL IR. Although other systems for tracking FIRRTL analyses have evolved over time, the ubiquity of pattern-matching on these fields has lead most core and custom transforms to be written against WIR, rather than IR. This PR unifies the IRs by adding the fields that would be in an "augmented" WIR node directly into the corresponding IR node; i.e., the "type" and "kind" fields from WRef are added directly to the definition of the Reference case class, while these "repetitive" WIR case classes are removed entirely. -------------------- SOURCE-COMPATIBILITY ADAPTERS --------------------- Several object methods are added to WIR.scala to maintain source-compatiblity for passes that used WIR. These objects define factory methods and unapply methods, so passes that relied on implicit case class factories or pattern matching for the removed WIR types will remain perfectly source-compatible. However, these do not guarantee compatibility at the binary level. The types of the removed WIR case classes are also added as type aliases to the top-level firrtl package, which allows code that relies on explicit constructor calls or reflection to retain source-compatibility. Finally, additional explicit factory methods are added to the companion objects of the newly-augmented IR case classes, which allows user code to avoid having to specify any of the new analysis fields. Existing code that created non-WIR IR nodes will be able to continue using the previous factory signatures, which will cause all omitted analysis fields to be set to Unknown. ---------------------- UNMITIGATED API CHANGES ------------------------- While passes that used WIR will be source-compatible with this change, there is one significant change that affects any pass currently using non-WIR IR: the signatures of pattern-matching cases for Reference, SubField, SubIndex, SubAccess, and DefInstance must change to accommodate the extra fields. This cannot be worked at the API level due to restrictions on unapply overloading, but it could theoretically be solved with macros or other static rewriting. However, only four core transforms (RemoveProto, ToWorkingIR, Dedup, and RemoveChirrtl) use non-WIR IR, and it is expected that no user code currently relies on it, so the expected migration strategy is simply to change the small fraction of code relying on these nodes.

2020-04-22Mixin DependencyAPIMigration to all TransformsSchuyler Eldridge
This mixes in the new DependencyAPIMigration trait into all Transforms and Passes. This enables in-tree transforms/passes to build without deprecation warnings associated with the deprecated CircuitForm. As a consequence of this, every Transform now has UnknownForm as both its inputForm and outputForm. This PR modifies legacy Compiler and testing infrastructure to schedule transforms NOT using mergeTransforms/getLoweringTransforms (which rely on inputForm and outputForm not being UnknownForm), but instead using the Dependency API.

2019-11-14Use getName instead of getSimpleNameSchuyler Eldridge
This changes uses of `getSimpleName` to `getName`. The former throws idiotic exceptions under Java 8, e.g., `getSimpleName` will fail if used on a class inside an object. This fixes a bug where any call to the `name` method of a custom transform defined inside an object (or in an environment wrapping things in objects like a REPL) will throw a malformed class name exception. E.g., if you do this and run with `-ll info` or your custom transform deletes annotations. Signed-off-by: Schuyler Eldridge <schuyler.eldridge@ibm.com>
