      Finish streamlined implementation of RegisterFile · f26ba638
      Jens Korinth authored
      * entirely based on Queues now, fixed firing logic
      * still with workaround for problem in Queue with optional fields
      * simplified ProgrammableMaster
      * changed Registers write method to return Response instead of Boolean
      * switched completely to Spec testing: register files are generated
        ad-hoc, corresponding master program and testing steps are
        automatically generated

      Fixed naming issues in packages · a24a7684
      Jens Korinth authored
      * new scheme: chisel.axi is the main package
      * chisel.axi.Axi4 contains the full axi defs
      * chisel.axi.Axi4Lite contains the lite defs
      * chisel.axi.axi4 contains full Axi4 impls
      * chisel.axi.axi4lite contains lite impls
      * same applies for the generators, matching structure

      WIP: Implement generic spec testing for RegisterFile · bb347461
      Jens Korinth authored
      * moved DataWidth from top axi to Axi4/Axi4Lite objects
      * cleaned generators, adopted new naming structure
      * implemented generators for arbitrary register files
      * master actions improved, simpler constructors
      * master actions can be automatically generated from register file
      * need to clean up the namespaces etc. - gotten really messy

      Fix test problems in RegisterFileSpec · 318d789b
      Jens Korinth authored
      * fixed some issues in ProgrammableMaster regarding wrong types of the
        response channels (was using old approach, direct UInt)
      * fixed some issues in the register file spec, regarding peek/poke of
        non-IO fields, tests are functional

      Axi4LiteRegisterFile: Implement config register file · 3d7635a0
      Jens Korinth authored
      * AXI4Lite interface
      * flexible ControlRegister class hierarchy: constants, single values,
        virtual registers (callbacks)
      * implemented unit test cases
      * had to implement Axi4LiteProgrammableMaster for batch testing
