#475 The sky130_ef_fd_sc spice file for decap_12 is not pin compatible with the sky130_fd_sc_hd version. Issue created by d-m-bailey Version 1.0.493 and later From

The xschem symbol for

decap_12

has the pins in the

sky130_fd_sc_hd

order. This means that when using the symbol in a schematic, switching between the 2 libraries is not as simple as changing the prefix from

sky130_fd_sc_hd

to

sky130_ef_sc_hd

. Changing the pin order in the

sky130_ef_sc_hd__decap_12.spice

file may be sufficient, but since this file was generated from an extracted layout, changing the pin order in the original mag file might be a good idea too. The spice file is also referenced from verilog during device level LVS, but since the verilog to spice calls are by port name and not position, changing the port order in the spice subcircuit definition shouldn't cause a problem.
