is there diplomacy branch for chisel3?

[Edmond Cote]

This doesn't work too well together.

import chisel3._

import freechips.rocketchip.diplomacy._ // uses import Chisel._

[..] my chisel3 code here [..]

Error:(30, 58) Symbol 'type Chisel.package.Record' is missing from the classpath.

This symbol is required by 'class freechips.rocketchip.diplomacy.AutoBundle'.

Is there a branch that removes use of the compatibility layer from diplomacy?

Thanks,

Ed

I haven't run this code myself but here is an example using import chisel3._ and diplomacy: 

https://github.com/ucb-bar/testchipip/blob/master/src/main/scala/BlockDevice.scala

You *should* be able to interoperate compatibility code with chisel3._ code. The issue could also be a classpath/build system issue so if emulating the above code does not solve your problem, could you provide more information about how you're building everything?

Thanks,

Jack

I converted some code to chisel2 i.e. Input(Bool -> UInt(INPUT, 1 (and so forth) and was able to make some progress.

It's likely a build issue now.  I'll sporadically get the classpath dependency message or sometimes the unit test will run.  This is through trying different methods: IntelliJ, sbt, manually wiping workspace, invalidating caches, etc.

My build env might be different. I  am importing diplomacy via rocketchip in my build.sbt file.

// version to the artifact name.

libraryDependencies ++= Seq(

  "org.scalatest" %% "scalatest" % "3.0.4" % "test",

  "edu.berkeley.cs" %% "chisel3" % "3.1-SNAPSHOT",

  "edu.berkeley.cs" %% "firrtl" % "1.1-SNAPSHOT",

  "berkeley" %% "rocketchip" % "1.2"

adding -Ylog-classpath (which is suggested for debug) to scalacOptions occasionally fixed the problem :)

Will report back once I make progress.  If you/anyone has hints, it'd be appreciated!

Ok, here's the issue.  Always helps to step away for an hour or two.

My build was referencing both  chisel[..].jar and chisel3[..].jar (see red and orange)

  directory classpath: /home/edc/.ivy2/local/berkeley/macros_2.11/1.2/jars/macros_2.11.jar

  directory classpath: /home/edc/.ivy2/local/edu.berkeley.cs/hardfloat_2.11/1.2/jars/hardfloat_2.11.jar

  directory classpath: /home/edc/.ivy2/local/edu.berkeley.cs/firrtl_2.11/1.1-SNAPSHOT/jars/firrtl_2.11.jar

  directory classpath: /home/edc/.ivy2/cache/edu.berkeley.cs/chisel_2.11/jars/chisel_2.11-2.2.38.jar

  directory classpath: /home/edc/.ivy2/local/edu.berkeley.cs/chisel3_2.11/3.1-SNAPSHOT/jars/chisel3_2.11.jar

The dependency on chisel[..].jar was from my hardfloat built which wasn't picking up the correct version.

[info]   | +-edu.berkeley.cs:hardfloat_2.11:1.2 [S]

[info]   | | +-edu.berkeley.cs:chisel_2.11:2.2.38 [S]

Thanks for sending the example and your offer of support.

I looked at this repo as I'm trying to figure out how to incorporate some rocket chip blocks into my design, but I can't see from the repo how to add rocket chip files to the build path.  The build.sbt file is very minimal.

I tried adding rocket-chip as a submodule and adding this line to my build.sbt:

unmanagedSourceDirectories in Compile += baseDirectory.value / "rocket-chip" / "src"

But this results in a large number of errors.  Is there a canonical way to include "library" repositories into a project?
