Tim Edwards 577cc12fe0 Implemented fix from early issue #16. Finally decided to pull the 
trigger on this one in the hopes that it helps prevent user error
in implementing input pull-up and pull-down on GPIO pins.

kareem aaa3b863e5 reharden!: gpio_control_clock 
- add met5 obs to avoid drc with the top level pdn

!important: still need to use the latest openlane to replicate
 2022-10-05 07:03:11 -07:00
Tim Edwards 7276623d3c Corrected the pull-up definition and revised the CSB definition to 
match the corrected defintions (namely, pull-up is configuration
0x0801, and pull-down is configuration 0x0c01).

Tim Edwards de9605a01b Modified the mgmt_protect module to change the tristate outputs to 
zero level outputs when the user project area is powered down.
That allows the synthesis tools to buffer these outputs.  The
protection from floating inputs is left as-is, but all logic that
was unnecessary to be specified by gate instances has been changed
to RTL.  This leaves only a handful of signals (logic analyzer input,
user IRQ, and wishbone data out and acknowledge out) to be handled
by explicit logic gate instances.

kareem 7c524edd31 openlane(wip)!: housekeeping 
~ fix typo in referencing variables in sdc file

with cts and diode insertion

Tim Edwards dd6088e013 Corrected the instance name of the topmost GPIO defaults block on 
the left hand side of caravan from gpio_defaults_block_14 to
gpio_defaults_block_25.  Otherwise, the script that generates the
custom user configuration won't be able to change the defaults
for GPIO 25.

kareem acf92c3460 views: update gpio_control_block gds 2022-09-27 07:42:32 -07:00
kareem 85f7f86c4e reharden!: gpio_control_block 
- high level changes:
* add larger buffers on output ports
* add buffers on input ports
* adjust sdc file increasing output load and setting a high transition

- detailed changes:
* add interactive script for openlane where the order of events is a bit shuffled
	- to add obstruction before pdn
	- to manually insert buffers on some ports
	- to manually remove buffers inserted by synthesis on for example serial_clock_out
* change openlane config adding extra row and columns to increase the space and fit the
added buffers
* change config to enable buffering
* increase density for better placement?
* change the cell exclude list. some excluded cells didn't make sense
* ef decap cells break dynamic sims?
* add custom pdn script for to duplicate the old pdn

- misc changes:
* fix openlane makefile to properly detect interactive script

!important still need to run dynamic simulations
!important depends on some updates to openlane
