2016-09-12Rework map functions as class methodsjackkoenig
Changed code from match statements in Mappers.scala to methods on the various IR classes. This allows custom IR nodes to implement the mapper functions and thus work (ie. not match error) when map is called on them. This also should have a marginal performance increase because of use of virtual function calls rather than match statements.

2016-09-12Bug fix -- remove all empty expressions after ReplSeqMem passes (#294)Angie Wang
* Bug fix -- remove all empty expressions after ReplSeqMem passes * Added test to make sure ReplSeqMem can handle BundleType SMem (EmptyExpression leakage)

2016-09-06remove unnecessary mappers in NamespaceDonggyu Kim
there's a big stack overhead with mappers

internal implementation for flatMap seems to be inefficient
2016-09-06Address style feedback and add tests for getConnectOrigin utilityAngie
2016-09-06Support optionally filling write mask to data width via transform input ↵Angie
config file
2016-09-06Expanded annotations for valid memory sizesAngie
2016-09-06Edited conf generation to handle mem namespace collisionAngie
* Also started separate pass for annotating valid memory
2016-09-06Made the connect origin function more powerfulAngie
* It analyzes through statements that ConstProp would've optimized * Edge case wmask can be removed (pass tries harder to figure out that wmask = wen)
2016-09-06Added simple unit test for ReplSeqMemAngie
2016-09-06Added back support for conf writing.Angie
* Conf file info is passed in through annotations. * A pass should have its own set of sub-arguments delimited by :
2016-09-06Changed wmask to convert from VecType to UIntAngie
* Instead of filling the whole data width * Added helper functions in MemUtils
2016-09-06Replace DefMemories with wrapped black boxAngie
* Note, this version uses Albert's toBitMask function, * which expands the bit mask to be the full data width (similar to Chisel2 output) * Black boxes only have wmasks as needed
2016-09-06Pulled out duplicate memory annotationsAngie
* Annotate reference * Changed memory port names to RWx, Wx, Rx, etc. and reconnected nodes
2016-09-06Corrected counting for VectorTypes in MemUtilsAngie
* Was originally adding one extra set of things (to -> until) * MemPortUtil conditionally includes wmask, if necessary Changed endian-ness of write data/mask to match convention (little endian)
2016-09-06Pulled out memory annotation (write mask)Angie
* Annotates all sequential memories that can be black boxed. * Annotates sequential memories that don't need write masks.
2016-09-06Generated *.conf file for unique sramsAngie
2016-09-06Minor utility changes.Angie
* Corrected names to match current RW port spec * Added Jack's Namespace on Circuit
2016-09-06Added starter code for SMem replacementAngie
2016-09-05Change null statement to empty begin end (#264)Colin Schmidt
this eliminates warnings in recent versions of VCS
2016-08-25emit wires instead of registers for invalid randomizationHoward Mao
Before, the verilog emitter would connect registers to the invalid ports and use random initialization on the generated registers. It is better to generate wires instead and use random assignment on the wires.
2016-08-25Finer grained control over randomizationHoward Mao
We previously had `ifdef guards on some parts of the emitted verilog to control whether some registers or nets should be given random initial values. These guards were all dependent on the RANDOMIZE macro. However, there were actually three separate cases being controlled 1. Giving random values to disconnected wires 2. Random initialization of registers 3. Random initialization of memories It is possible that the designer would want to switch these three on or off independently in simulation. For instance, the latter two are usually safe because registers and memories will get some definite binary value at power on in the actual circuit, but the first one can be quite dangerous because the undriven wire could be metastable. This change provides separate macros for each of the three sets of guards so that they can be controlled independently.
