2022-10-17Add opt-in AutoCloneType for Records (backport #2781) (#2785)mergify[bot]
* Add opt-in AutoCloneType for Records (#2781) There is a new trait, chisel3.experimental.AutoCloneType that is mixed in to Bundle and can optionally be mixed in to user-defined Records. The compiler plugin prints a deprecation warning on any user-defined implementation of cloneType, telling the user to mix in AutoCloneType before upgrading to 3.6.

2022-07-06Refactor TruthTable.apply and add factory method for Espresso (backport ↵mergify[bot]
#2612) (#2620) * Refactor TruthTable.apply and add factory method for Espresso (#2612) Improves performance of creating TruthTables by processing entire BitPats rather than individual bits. New TruthTable factory method enables constructing TruthTables with semantics of OR-ing output BitPats together rather than erroring when multiple terms have the same input BitPat. This alternative factory method matches semantics for the output format of Espresso.

2022-06-16Define leading '_' as API for creating temporaries (backport #2580) (#2581)mergify[bot]
* Define leading '_' as API for creating temporaries Chisel and FIRRTL have long used signals with names beginning with an underscore as an API to specify that the name does not really matter. Tools like Verilator follow a similar convention and exclude signals with underscore names from waveform dumps by default. With the introduction of compiler-plugin prefixing in Chisel 3.4, the convention remained but was hard for users to use unless the unnnamed signal existed outside of any prefix domain. Notably, unnamed signals are most useful when creating wires inside of utility methods which almost always results in the signal ending up with a prefix. With this commit, Chisel explicitly recognizes signals whos val names start with an underscore and preserve that underscore regardless of any prefixing. Chisel will also ignore such underscores when generating prefixes based on the temporary signal, preventing accidental double underscores in the names of signals that are prefixed by the temporary.

2022-06-01Add formatted Printable interpolator `cf` (#2528) (#2553)mergify[bot]
This is a formatted version of the p"..." interpolator analogous to Scala's f"..." interpolator. The primary difference is that it supports formatting interpolated variables by following the variable with "%<specifier>". For example: printf(cf"myWire = $myWire%x\n") This will format the hardware value "myWire" as a hexidecimal value in the emitted Verilog. Note that literal "%" must be escaped as "%%". Scala types and format specifiers are supported and are handled in the same manner as in standard Scala f"..." interpolators.
