kareem 6d1d618974 reharden!: gpio_control_block 
- rtl updated
~ add one column to the right to pass placement congestion
~ density adjusted (probably has no effect)
+ manually add isosubstrate layer in mag and gds from older iterations

!important still need to run dynamic simulations
!important depends on some updates to openlane
!important need to be able to recreate using newer openlane versions

Fix the simple_por to (logically) isolate the 1.8V and 3.3V grounds. (#90) 
* Fix the simple_por to (logically) isolate the 1.8V and 3.3V grounds.
This commit does the following:
(1) Corrects the xschem simple_por schematic to separate the 1.8V and 3.3V grounds.
(2) Corrects the xschem simple_por symbol to separate the 1.8V and 3.3V grounds.
(3) Corrects the xschem testbench to connect to both grounds of simple_por.
(4) Corrects the simple_por layout to remove the 1.8V logic from the
    3.3V ground and connect it instead to the 1.8V ground.
(5) Extends the top-level power routing of caravel and caravan to
    make a better connection to the simple_por 1.8V ground.
(6) Adds an LVS script to properly check the simple_por layout against the
    xschem-generated schematic netlist.

NOTE: None of these modifications change the function of any circuit.  The
1.8V and 3.3V ground nets are only logically separated in the netlists but
share the substrate.  This fix cleanly defines the 1.8V and 3.3V grounds
within the simple_por, where they were previously mingled.  It also ensures
that the full LVS for caravel and caravan can now include the simple_por at
the transistor level and still pass.

* Updated the GDS of simple_por (previously did not remove GDS_FILE
from the .mag file and so it just overwrote the original GDS file
with itself).

* Corrected a route to simple_por in the top level of both caravel
and caravan that was shorting to the extra metals put on top of
the substrate contact across the top (bottom, in the top level)
of the simple_por layout.

Tim Edwards 53abff5bbf This commit fixes the issue with the user ID programming block not 
getting changed by "make ship" because the build is done in a place
where the path pointer to the user_id_programming GDS still points
back to the original caravel repository, not the user project
repository.  The user_id_programming GDS was removed (no longer used),
the user_id_programming.mag file was modified to remove the path
pointer to the GDS, and the set_user_id.py script was modified to
make changes directly to the user_id_programming.mag file instead of
the GDS.  An additional method was added to the set_user_id.py script
to modify the gate-level verilog/gl/user_id_programming.v to make
the user ID correct for gate-level testbench simulations.

Tim Edwards f53590d4b5 Split the layout of the GPIO defaults block into three versions, for the 
three parameterized values used in the RTL verilog.  Modified the
"user_defines.v" file to create verilog definitions that match the C-style
definitions from "defs.h", for convenience/simplicity.

Tim Edwards 33140b67a5 Edited the gpio_defaults_block layout like the user_id_programming 
cell to have landing sites for vias on both the HI and LO pins of
each conb_1 cell, in preparation for via programming.
