Tim Edwards cfeb62dfb4 A number of changes to the caravan netlists, (1) to correct for 
problems that had been fixed recently in caravel, and which cause
the caravan testbench to break, but which were not noticed;  (2)
corrected the count of gpio_control_block modules, which was one
off, with two of them overlapping (not sure how that even passes
simulation, but it did);  (3) fixed a power connection in the
caravel chip_io, which should have caused chip_io to fail LVS,
so apparently LVS was not run on chip_io. . .
 2021-11-22 09:46:21 -05:00
Tim Edwards 1eb023d973 Added isolated substrate markers in mgmt_protect_hv, should fix the 
last of the LVS issues.
 2021-11-21 23:04:45 -05:00
Tim Edwards 6eb8bb54de Several more LVS corrections, including fixing a label in chip_io that 
got removed from its net by a chang in the LEF view of an I/O pad, and
a lack of declaration of an array to attach to pwr_ctrl_out in the
verilog, which is valid verilog but netgen can't know the bus size
without the no-connect net being declared.  The remaining issue has to
do with separation of ground domains in the mgmt_protect block.
 2021-11-21 22:58:39 -05:00
Tim Edwards 5262f35610 Modifications done as part of LVS on the caravel top level. 2021-11-21 22:07:16 -05:00
Tim Edwards 60bdc7e6a4 Moved some supply lines over in chip_io_alt for Caravan to make it 
more compatible with the routing that was copied over from Caravel.
 2021-11-21 13:00:44 -05:00
Tim Edwards d87d60cb9b Finished first draft of the caravel power routing (prior to LVS). 2021-11-21 12:41:46 -05:00
Tim Edwards 29dbc77591 More power routing, still a work in progress. 2021-11-20 22:53:18 -05:00
Tim Edwards 6570429234 Continued work on the power routing. Also updated the management 
core wrapper view with the LEF view from caravel_pico.
 2021-11-20 22:04:46 -05:00
Tim Edwards 8f75362f82 Start of power routing. 2021-11-20 18:04:43 -05:00
Tim Edwards b0d3217280 Replaced the gpio_defaults_block_0000.mag layout with gpio_defaults_block.mag 
so that it contains a valid layout after processing by Openlane (since the
verilog module is named gpio_defaults_block).  Corrected the orientation of
the defaults block layouts on the right side of Caravel and erased the
incorrect routing there.  Reinstated the copyright, user ID text, open source
logo, and Caravel logo.  Revised the gen_gpio_defaults.py script to handle
the first five GPIOs in the same way as the others, although as fixed entries
which cannot be modified by the user project designer.

Tim Edwards bb1c9fe528 Removed two references for single-macro verilog files that are no 
longer in the PDK but have been folded into larger library files.

verilog library, the verilog testbenches once again pass.

the new clamped3 cell from open_pdks.
