parameter not find in freechips.rocketchip.config

[tangjiaping]

when i build verilog, i got the error as follows:
rocket-chip/src/main/scala/amba/axi4/Credited.scala:12:64: not found: type Parameters
[error] class AXI4CreditedBuffer(delay: AXI4CreditedDelay)(implicit p: Parameters) extends LazyModule

I open the Credited.scala file, and found that import freechips.rocketchip.config.Parameters. But i can't find the config directory. Hope someone can tell me what i should do to resolve the error.

Are you sure about that? import org.chipsalliance.cde.config.Parameters should be the correct import. Maybe you are using older version of Rocketchip. Look this commit "b6bf0bc"
