This package contains a generic implementation of a bi-directional crossbar switch in the Chisel hardware description language. You can include it in your own Chisel or Verilog projects.
To install, run "sbt publish-local" and then add the following dependency line to your build.sbt file.
"com.mao.howard" %% "chisel-crossbar" % "0.1-SNAPSHOT"
The file CrossbarSwitch.scala has some comments explaining how it should be used.
// this creates a switch with a forward path of width 8
// a backward path of width 16
// 4 ports on the 'left'
// and 8 ports on the 'bottom'
val switch = Module(new CrossbarSwitch(8, 16, 4, 6)
// this sets up the switch so that port 2 on the left
// and port 4 on the bottom are connected to each other
switch.io.fw_left(2) := UInt(22)
switch.io.bw_bottom(4) := UInt(54)
switch.io.select(4) := UInt(2)
