Sounds great!

I think this would be somewhat difficult to do in an arbitrary way. Right
now, the bit names - if they're defined at all - come to gpsim as constant
defined in the .cod file. There is no type information associated with
them. So somehow you would have to know what the bit names are. This
information is present in the form of enumerated constants throughout the
files supporting the various pic subsystems. Unfortunately, the ascii
names for these constants aren't avaliable. How were you thinking about
implementing this?

Version 0.17.1 (which only one other person besides me has seen) contains
a new cli option for the processor command. "processor pins" will display
a tabulated/quasi graphical, ASCII representation of a pic processor and
show pin names, pin numbers, and the pin states (only H and L for high and
low - analog states are not shown yet).
Here's an example dump for the c84:
+--+---------\/---------+--+
L | 1| porta2 porta1 |18| L
L | 2| porta3 porta0 |17| L
L | 3| porta4 |16|
| 4| |15|
| 5| |14|
H | 6| portb0 portb7 |13| H
H | 7| portb1 portb6 |12| H
H | 8| portb2 portb5 |11| H
H | 9| portb3 portb4 |10| H
+--+--------------------+--+
The new code is cmd_processor.cc in the function dump_pins(). I added a
couple of new base class functions to the pic_processor class that will
support access to the pin names, pin states, and to package stuff in
general. We'll want to place wrappers around these in interface.cc . (At
some point, interface.cc is going to have to be split...)
At some point I'd like to also show the stimuli attached to the pins.
(Ralf knows most of what I'm going to say next). The gui version should be
able to easily duplicate this basic functionality. However, to make it
useful, cross references such as those that are present between the file
registers and the register_window(s) will also be needed. This will allow
the window to be dynamically updated. An added bonus would be to toggle a
pin state by simple clicking on the state indicator.
When we get to the point where stimuli are an integral part of the gui it
would be nice to be able to edit the stimuli that attached to the pins.
BTW, the latest development version of gpsim can be obtained from:
