I am working on Rocket Chip Generator, which is a SoC written in Chisel.
My objective is to extract the Floating-Point Unit, in order to synthesize it and study its power consumption/area ...etc. separately from the rest of the SoC.
So I cloned the project and tried to create a dedicated TestHarness where I only instanciate an FPU. This is an example code of what I did (very similar to TestHarness
package freechips.rocketchip.system
import Chisel._
import freechips.rocketchip.config.Parameters
import freechips.rocketchip.devices.debug.Debug
import freechips.rocketchip.diplomacy.LazyModule
import freechips.rocketchip.rocket._
// importing FPU class
import freechips.rocketchip.tile._
class FPUTestHarness() (implicit p: Parameters) extends Module {
val io = new Bundle {
val dummyIn = Bool(INPUT)
val dummyOut = Bool(OUTPUT)
}
// The parameters of the FPU
val fpu_params = FPUParams(
fLen = 32 // default is 64
divSqrt = false // default is true
// sfmaLatency = 3, // default
// dfmaLatency = 4 // default
)
val fpu = Module(new FPU(fpu_params)(p))
}
The problem is that the implicit parameter p (of type Parameters) doesn't contain something called TileKey, which is needed I don't know where. Apparently the implicit parameter p, passed to FPUTestHarness doesn't contain that information. How can I resolve that? Is it possible to hardcode that somewhere for example?

It seems that you use the config as "DefaultConfig". Error log states that you did not specify TileKey parameter in this config. Adding TileKey parameter will resolve the issue. DefaultConfig is defined in rocket-chip/src/main/scala/system/Configs.scala
I was trying to run a play sbt multi-project using command 'sbt "project subproject" ~run'
But received following error:

I think what you want is sbt "~subproject/run"
I had this same problem and, it was because I was running sbt . (with a trailing period).
Just using sbt or sbt [command] solved the problem for me
After adding the following method to map case classes to Map or js.Dictionary - and I've tried now five or six variants of the following - my code compiles fine and without warnings, but then hits errors at the fastOptJS sjs linking stage.
The method
def ccToMap(cc: AnyRef) =
(Map[String, Any]() /: cc.getClass.getDeclaredFields) {
(a, f) =>
f.setAccessible(true)
a + (f.getName -> f.get(cc))
}
Note that all the variants I have tried do the same thing in a slightly different manner.

What I've tried
Being unfamiliar with the details of the linker I am only able to try some "obvious" diagnostics:
Whether I call the method or not, this error is thrown (it doesn't have to be in the code path, so this is getting thrown when the method itself is linked)
The Map type itself works just fine as an argument to the function where I am trying to invoke this
I know to a certainty that iff this method (or similar) is present, then I get the above linker error. (Without, no error.)
Any tips on how to proceed, debug, etc are appreciated.
Alternatively, any tips on how I may convert a case class to a Map without the above-style (reflection-based) function, please let me know
You simply can't use Java reflection in Scala.js:
Java reflection and, a fortiori, Scala reflection, are not supported. There is limited support for java.lang.Class, e.g., obj.getClass.getName will work for any Scala.js object (not for objects that come from JavaScript interop).
Use macros for this instead. See e.g. Scala Macros: Making a Map out of fields of a class in Scala
I think this should be due to some issues in my enviroment, I can't figure this out so I am posting a question.
I created a new play 2.1.3 project (scala 2.10.2).
When I run play for the first time (no file is edited at this stage) and run the test sbt command, I get the following error.

UPDATE - Problem Fixed
These files somehow managed to get into classpath,
rm /Library/Java/Extensions/log4j-1.2.15.jar
rm /Library/Java/Extensions/slf4j-api-1.5.8.jar
rm /Library/Java/Extentions/slf4j-log4j12-1.5.8.jar
I don't know which program placed these files.
Play logger will be called by default even if you don't use it. Check your application.conf
it contains something like:
# Root logger:
logger=ERROR
# Logger used by the framework:
logger.play=INFO
# Logger provided to your application:
logger.application=DEBUG
and Play.logger uses log4j and slf4j both as you can see above . So you need to configure them properly .
Check this question for setting up slf4 and log4j How to get SLF4J "Hello World" working with log4j?
I'm getting this exception when running the scalatra specs2 example from the scalatra docs:
ThrowableException: org.eclipse.jetty.http.HttpGenerator.flushBuffer()I (FutureTask.java:138)
Here is the test code (starting on line 5, skipping imports):
class MyAppTest extends MutableScalatraSpec {
addServlet(classOf[MyApp], "/*")
"GET / on AdminApp" should {
"return status 200" in {
get("/") {
status must_== 200
}
}
}
}
Here is the app definition:
class MyApp extends ScalatraServlet {
get("/") {
"aloha"
}
}
I'm using scalatra-specs2 2.0.4 and scala 2.9.1. I'm running an embedded jetty server using xsbt-web-plugin 0.2.10 with sbt 0.11.2. The test was executed using sbt test.
Here is the full trace:

This is the only search result that has turned up so far:
Fragment Evaluation Error.
Can someone point me in the right direction?
Thanks,

Still unsure of the root cause, but the test executes successfully after rolling jetty-webapp back from 8.0.3.v20111011 to 7.6.0.v20120127.
You probably have a conflict in your dependencies, more specifically with the Jetty library version. Since the "flush" method on HttpGenerator has changed between Jetty 6 and Jetty 7, you might be getting a "NoSuchMethodFoundError" which explains the strange "org.eclipse.jetty.http.HttpGenerator.flushBuffer()I" signature in the exception message.
This also explains why you get a "fragment evaluation error" and not a regular failure as explained in the link you mentioned.
If you give a go at the latest specs2-1.10-SNAPSHOT, you will get a better message for "fragment evaluation error" showing 'NoSuchMethodError' when that happens. This will help you diagnosing the issue faster.
