Hi, For dlrtn, when I want to do LVS, it seems that I need the schematic of this block. I just imported dlrtn block in Xschem and Magic, but when I do LVS, there is some errors. Does anyone know how I can fix the issue? Thanks

Apparently the symbol isn't being exported from xschem; I'm not sure why. In netgen, it is shown as having the default pin assignments (numbered 1 to 8) rather than the given pin names (which would be the four explicit pins plus the four implicit power pins, passed as parameters of the symbol instance).

Thank you for your reply. How can I export the symbol in Xschem?

Normally you'd just have a

.include

statement in the output (created with a

code

block in xschem, I think) which includes the PDK file that defines the netlist for the symbol, if the symbol is standalone and does not have an associated transistor-level schematic (which generally, it won't, if there is a PDK library that has all the netlists in it).

@sepide asgari you need to include the standard cell netlists. They are all in one file:

.include /path/to/your/pdk/sky130A/libs.ref/sky130_fd_sc_hd/spice/sky130_fd_sc_hd.spice

Thank you for your response. Do you mean I should include the standard cell netlists like the attached picture?

the .include in the picture seems incomplete. Yo are missing the

/sky130_fd_sc_hd.spice

Hi, Thank you. It works.
