mrg 357f967a93 Leave supply routing to new helper functions. 2022-05-11 11:01:14 -07:00
mrg b6c3580e24 Fix width of replica routes. Don't enclose pins if they overlap sufficiently. 2022-05-09 11:44:46 -07:00
mrg 50045e54e8 Fix a couple supply routing issues. 2022-05-03 11:45:51 -07:00
mrg f8f3f16b1f Move delay line supply strap for pin access. 2022-05-02 16:42:14 -07:00
mrg b1bb9151c4 Reimplement off grid pins. 
Long pins aren't accessed on end pins anymore.
Fix problem with multiple non-enclosed space causing blockages.
Add partial pin offgrid enclosure algorithm.
 2022-05-02 15:43:14 -07:00
mrg 64f2f90664 Rework replica_bitcell_array supplies 
Uses layer and direction preferences in tech file.
Places straps on left/right or top/bottom.
 2022-04-19 08:50:11 -07:00
mrg 5e546ee974 New power strapping mostly working. 
Each module uses M3/M4 power straps with pins on the ends.
Works in all technologies for a single no mux, dual port SRAM.
 2022-04-05 13:51:55 -07:00
mrg 01a73b31e1 Fix power ring routing boundary bug. 2022-03-18 10:32:25 -07:00
mrg 7e7670581c Add some vertical/horizontal pins for sky130 only 2022-03-16 07:58:29 -07:00
mrg 8c911f70b9 Build changes. 
Don't pull docker since it will be build by CI.
Shuffle tests to stagger technologies and test types.
 2022-03-06 10:31:43 -08:00
mrg d69e55c2e3 Power routing changes. 
Make the power rails an "experimental_power" option and conditional.
Rename route_vdd_gnd to route_supplies everywhere for consistency.
 2022-03-06 09:56:00 -08:00
mrg 8b3c10ae79 Improvements to power routing. 
Improved the route horizontal and vertical pin functions to
create a single pin at the end.
Swapped A and B on wordline driver input for cleaner routing
in most technologies.
Fixed vertical supply routing in port_address.
