Learn expandExpr how to handle Let expressions.
Matthijs Kooijman [Thu, 29 Jan 2009 16:43:10 +0000 (17:43 +0100)]
Make full_adder simpler.
Matthijs Kooijman [Thu, 29 Jan 2009 16:42:42 +0000 (17:42 +0100)]
Improve error message for createSignalAssignments.
Matthijs Kooijman [Thu, 29 Jan 2009 16:42:09 +0000 (17:42 +0100)]
Learn ExpandExpr how to handle simple case expressions.
Matthijs Kooijman [Thu, 29 Jan 2009 15:49:05 +0000 (16:49 +0100)]
Add a base case to splitTupleConstructorArgs.
Apparently we've never tried to find the end of the returned list before :-)
Matthijs Kooijman [Thu, 29 Jan 2009 15:48:30 +0000 (16:48 +0100)]
Learn expandExpr how to handle tuple construction.
Matthijs Kooijman [Thu, 29 Jan 2009 15:48:03 +0000 (16:48 +0100)]
Add a duplication hardware model.
Matthijs Kooijman [Thu, 29 Jan 2009 15:32:09 +0000 (16:32 +0100)]
Implement expandArgs in terms of expandExpr.
This makes expandArgs a lot more general.
Matthijs Kooijman [Thu, 29 Jan 2009 15:31:31 +0000 (16:31 +0100)]
Add a double invertor model.
Matthijs Kooijman [Thu, 29 Jan 2009 15:21:12 +0000 (16:21 +0100)]
Learn expandExpr how to expand Application.
Matthijs Kooijman [Thu, 29 Jan 2009 14:32:32 +0000 (15:32 +0100)]
Let expandExpr error out on unsupported expressions.
Matthijs Kooijman [Thu, 29 Jan 2009 14:32:09 +0000 (15:32 +0100)]
Add an invertor hardware model.
Matthijs Kooijman [Thu, 29 Jan 2009 14:26:35 +0000 (15:26 +0100)]
Rework the VHDL generation to be more bottom up.
The new function expandExpr does something similar to getInstantiations
(and is used instead of it now), but follows a more bottom up approach,
generating new signals as needed and only connecting these signals to
ports at the very end. This allows for more general handling of nested
expressions and will probably make things less complex.
For now, this means that the Translator can only translate the trivial
"wire" hardware model, more support coming up.
This also means that we're using VHDLId's in almost all SignalNameMaps
now, which reduced the conversion from String.
Matthijs Kooijman [Thu, 29 Jan 2009 14:22:35 +0000 (15:22 +0100)]
Add a trivial "wire" hardware model.
Matthijs Kooijman [Thu, 29 Jan 2009 12:29:07 +0000 (13:29 +0100)]
Rename PortNameMap to SignalNameMap and make it a dependent type.
Matthijs Kooijman [Thu, 29 Jan 2009 12:16:47 +0000 (13:16 +0100)]
Move around some functionality.
This moves some code from getPortMapEntry into a new function expandArgs,
and also prepares for generating signal declarations in addition to
component instantiations.
Matthijs Kooijman [Thu, 29 Jan 2009 11:26:29 +0000 (12:26 +0100)]
Reorder and comment things a bit.
Matthijs Kooijman [Thu, 29 Jan 2009 10:43:18 +0000 (11:43 +0100)]
Use uniqueName to make component instantiations unique.
Matthijs Kooijman [Thu, 29 Jan 2009 10:42:50 +0000 (11:42 +0100)]
Add a uniqueName function.
This function appends a unique number to names to make the names unique.
Matthijs Kooijman [Thu, 29 Jan 2009 10:36:34 +0000 (11:36 +0100)]
Add some comments.
Matthijs Kooijman [Tue, 27 Jan 2009 16:34:38 +0000 (17:34 +0100)]
Use spaces instead of tabs.
Matthijs Kooijman [Tue, 27 Jan 2009 16:32:56 +0000 (17:32 +0100)]
Put getInstantiations in the State monad.
Matthijs Kooijman [Tue, 27 Jan 2009 15:01:57 +0000 (16:01 +0100)]
Put getArchitecture inside the State monad.
Matthijs Kooijman [Tue, 27 Jan 2009 14:50:44 +0000 (15:50 +0100)]
Make the state monad calling code more pretty.
Matthijs Kooijman [Tue, 27 Jan 2009 14:24:17 +0000 (15:24 +0100)]
Run mkHWFunction and addFunc in a State monad.
This uses a state consisting of a VHDLSession. The invocation of these
functions is a bit ugly now, that will be cleaned up next.
Matthijs Kooijman [Tue, 27 Jan 2009 13:36:17 +0000 (14:36 +0100)]
Derive Show for the data types we define.
Matthijs Kooijman [Thu, 22 Jan 2009 19:34:54 +0000 (20:34 +0100)]
Remove the Args constructor, just use a list instead.
Matthijs Kooijman [Thu, 22 Jan 2009 19:32:18 +0000 (20:32 +0100)]
Look up the port names in the session when generating an architecture.
Matthijs Kooijman [Thu, 22 Jan 2009 19:28:34 +0000 (20:28 +0100)]
Generate a HWFunction for the function that is being generated.
Matthijs Kooijman [Thu, 22 Jan 2009 16:40:04 +0000 (17:40 +0100)]
Lookup input port names for instantiations in the session.
This replaces the previously hardcoded portnames.
Matthijs Kooijman [Thu, 22 Jan 2009 16:37:14 +0000 (17:37 +0100)]
Make getPortMapEntry accept a PortNameMap.
Matthijs Kooijman [Thu, 22 Jan 2009 16:33:51 +0000 (17:33 +0100)]
Pass around a session variable.
This session variable stores a list of available functions and a number
for generating unique names. So far, the session is only used to lookup
output port names and is read only (ie, not returned from functions).
Matthijs Kooijman [Thu, 22 Jan 2009 15:33:44 +0000 (16:33 +0100)]
Use ForSyDe.Backend.VHDL modules to generate VHDL.
The current code is still a bit hacky, but no longer contains hardcoded
VHDL and instead builds a VHDL AST which is then printed by modules from
ForSyDe.
Note that this uses internal ForSyDe modules. ForSyDe was modified to
expose these internal modules.
Matthijs Kooijman [Thu, 22 Jan 2009 13:55:47 +0000 (14:55 +0100)]
Remove the entity generation code.
Matthijs Kooijman [Wed, 21 Jan 2009 12:40:07 +0000 (13:40 +0100)]
Handle tuple constructors in expressions.
This enables a hardware model to have multiple output ports, using a tuple
type. The code is still a bit hacky and only works for two-tuples.
Matthijs Kooijman [Wed, 21 Jan 2009 12:38:15 +0000 (13:38 +0100)]
Let the Adders module export everything.
Matthijs Kooijman [Wed, 21 Jan 2009 12:37:56 +0000 (13:37 +0100)]
Add a haskell model for a half adder.
Matthijs Kooijman [Wed, 21 Jan 2009 10:52:37 +0000 (11:52 +0100)]
Add an error message.
Matthijs Kooijman [Wed, 21 Jan 2009 10:49:52 +0000 (11:49 +0100)]
Map output ports as well as input ports.
Matthijs Kooijman [Wed, 21 Jan 2009 10:48:58 +0000 (11:48 +0100)]
Generate input port names from the argument types.
This replaces the hardcoded list of input port names which was used for
testing before.
Matthijs Kooijman [Mon, 19 Jan 2009 15:47:35 +0000 (16:47 +0100)]
Add .gitignore file.
Matthijs Kooijman [Mon, 19 Jan 2009 15:45:52 +0000 (16:45 +0100)]
Intial import of some haskell programs.
Contains the following files:
* Adders.hs - Some Haskell modelling of hardware adders.
* Alu.hs - A haskell model of an (extremely) simple cpu.
* Bits.hs - Stuff relating to a basic "Bit" datatype.
* Inverter.hs - A haskell model of an inverter.
* Parser.hs - A simple haskell parser using Language.Haskell libraries.
* Shifter.hs - A haskell model of an interactive xor-shifter.
* Sim.hs - Some utilities to run hardware models.
* Translator.hs - A basic program that uses GHC to read Haskell code and
translates it into VHDL. This code is still very preliminary.
