      Minimize DataWidthConverter logic · 8e94f119
      Jens Korinth authored
      * direct reference of reset is discouraged
      * replaced all direct references with RegInits or removed reset
      * fixed overwrites of test runs (now each in separate dir)
      * added test directory to cleanFiles, will be removed on sbt clean

      DecoupledDataSource: repeat and non-pow2 sizes · 77b40f09
      Jens Korinth authored
      * repeat now also works with size which are not a power of 2
      * more complex Mux logic is only generated in case size is not a power
        of 2, otherwise identical as before
      * cleaned up a little and used new logging facilities to implement
        fine-grained info at each consumption

      Implement logging for Modules · 0e19c7ff
      Jens Korinth authored
      * implemented both hardware (runtime) logging and constructor logging
        (compile time)
      * mix-in trait Logging provides methods info, warn and error (and cinfo,
        cwarn, cerror resp. for constructor logging)
      * logging level is controlled by implicit Logging.Level, determined at
        each call, allows for selective logging

      Fix bug in DecoupledDataSourceSuite · 9749d045
      Jens Korinth authored
      * chisel3 is a little finicky with peek/poke: it seems only stuff in the
        io bundle of modules is really safe
      * needed to replace peeking in the internal mems, since that seems
        to crash the LoFirrtlEvaluator
      * all tests functional again

      DataWidthConverter: Fix full throughput · 79d6920e
      Jens Korinth authored
      * new full speed test suite failed: output may not block
      * fixed by adding new special case
      * achieves full speed & correctness now

      DataWidthConverter: Extend tests · df4586fa
      Jens Korinth authored
      * separated correctness from speed tests for DWC
      * correctness tests with slow queue in between and varying delays
      * full speed suite tests full throughput of data stream (may not block)
      * current implementation fails the latter

      Jens Korinth authored
      * DWC only worked correctly at full speed
      * delays caused lost nibbles, fixed now
      * added secondary test harness to test against a slow receiver

      DataWidthConverter: Fix bugs in implementation · 3f3fef24
      Jens Korinth authored
      * previous implementation was not capable of handling a continuous
        stream of data (continuity must be preserved to avoid congestion)
      * new implementation fixes this and several other minor issues
      * better unit test: now using inverted pairs of DWCs
      * makes testing code much simpler and data/waves easier to check
      * added additional tests to specify the required timing behavior
        (i.e., preserving continuous data streams)
