Michael Timothy Grimes 42719b8ec2 Fixing netlist_only errors. Removing netlist_only option from ptx because it must always generate layout for pbitcell. gds_write, drc check, and lvs check in local_check() are now in a 'if not OPTS.netlist_only' conditional. These functions will generate errors in netlist_only mode since there is no gds layout to write or check. 2018-09-12 01:53:41 -07:00
Matt Guthaus 8664f7a0b8 Converted all modules to not run create_layout when netlist_only 
mode is enabled.
