Merge pull request #122 from efabless/fix_direct_power_connections 
Fix direct power connections
 2022-10-06 11:33:41 -04:00
Tim Edwards 42805f767e Removed some references to mgmt_soc_litex files that had been added 
to caravel_netlists.v when attempting to determine if the
verification testbenches could be run from caravel referencing
caravel_mgmt_soc_litex instead of the other way around.  This file
has been reverted back to its original form.

Tim Edwards e2556cc11b Removed the SPARE_LOGIC_BLOCK ifdef...endif from around the spare 
logic in caravel.v and caravan.v.  These had been added to the
caravel_stanford branch because the spare logic blocks are not
usefully synthesizable.

Remove mgmt protect tristates

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

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 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

Tim Edwards 66fc0c6a06 Modified the GPIO control block to buffer the constant high/low outputs. 
Corrected the pad constant connections to all be in the correct domain
(1.8V or 3.3V).  Created a new "constant_block" module that generates
a single constant 1 and 0 value in the 1.8V domain, and used 7 of these
in the chip_io (and chip_io_alt) modules to create the 1.8V domain
constant signals for the seven pads belonging to the management (clock,
reset, flash SPI, and management GPIO).
