Tim Edwards fe21089505 Updated caravan with the same addition of four spare logic blocks 
as was made to caravel.
 2021-11-24 17:10:05 -05:00
Tim Edwards be98da0fe6 Added spare logic block to caravel layout and verilog GL, wired 
it to the power supply, and checked top-level LVS.

Tim Edwards 543fee18e3 Revised the spare logic block to make sure that all inputs are 
reachable from pins on the boundary once it's synthesized.
 2021-11-24 09:34:52 -05:00
Tim Edwards 2b156997cb Added a new module with "spare logic" for metal mask fixes. 2021-11-24 09:23:22 -05:00
Tim Edwards 9b1a18a15e Finished drawing all of the analog connections to meet cleanly at 
the user analog project boundary.
 2021-11-23 17:32:52 -05:00
Tim Edwards 0114df40ae Added additional power routing from the sides of Caravel to the 
user project power ring.  If that is incompatible with user
projects and/or the XOR check, then this commit might need to be
reverted.
 2021-11-23 16:49:23 -05:00
Tim Edwards 0ba8884b00 Added a motto for each chip. Just because. 2021-11-23 15:19:41 -05:00
Tim Edwards 1ff48245e8 Pushing final layout of Caravan, now LVS clean. 2021-11-23 14:06:14 -05:00
Tim Edwards 5d3f2a26f4 Corrected the Caravel layout and the Caravel and Caravan GL netlists 
to resolve the problem with the typo that caused the propagated
GPIO serial load, reset, and clock signals to get scrambled on the
user2 side.  Caravel is now LVS clean again (Caravan needs layout
work).
 2021-11-23 11:47:17 -05:00
Tim Edwards 08a2c90940 Made updates to correct LVS errors in caravan. Found one major error in the RTL 
verilog for both caravel and caravan.  Hand-edited the RTL and GL netlists to
correct this;  still need to correct the layouts.  The error causes the user1
side clock, load, and reset buffers to drive the user2 side as well as the user1
side, making a huge mess of the routing.  Will route this by hand.

Tim Edwards e86831b188 Final edits to make caravel LVS clean. 2021-11-22 16:51:35 -05:00
manarabdelaty aeffe4756a [DATA] Add caravan layout 2021-11-22 23:10:25 +02:00
manarabdelaty 38f64d08a3 [DATA] Add user_analog_project_wrapper and chip_io_alt gds/lef views 2021-11-22 23:08:25 +02:00
Tim Edwards cd68a2aeff Made several corrections to errors found in the netlists: (1) 
Fixed rstb_h, which was being input to low-voltage blocks.  (2)
Fixed flash_csb_ieb_core and flash_clk_ieb_core, which were not
output from housekeeping as they should be;  the solution was
to tie the INP_DIS lines low at the pad by connecting them to
the TIE_LO_ESD line.  This should probably be addressed in
housekeeping but would change the current pinout.
 2021-11-22 15:21:06 -05:00
Tim Edwards 1e14d3a4c5 Corrected the rstb_l signal in both caravan and caravel, and corrected 
the clock_core signal in caravan.
 2021-11-22 13:25:35 -05:00
Tim Edwards 515b5a54f2 Updates for LVS. Only LVS issue remaining for caravel is how to get the 
ground domains to extract independently.
 2021-11-22 12:00:55 -05:00
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.
