Matt Guthaus 3147b99ce0 Merge remote-tracking branch 'bkoppelmann/bit-sym' into dev 2020-01-29 11:24:09 -08:00
Bastian Koppelmann df9f351a91 Add custom cell properties to technologies 
this is technology specific database to store data about the custom
design cells. For now it only contains on which axis the bitcells are
mirrored. This is a first step to support thin cells that need to be
mirrored on the x and y axis.

Bastian Koppelmann 407bd026ee tech: Make m3_stack the power_grid stack for FreePDK45/scn4m 
explicitly stating the power_grid makes people porting a new technology
aware of this option.
