relative pathes for spice include files #4

Sourcerer commented 2023年03月20日 07:06:36 +01:00

When I tried to use the following .lib statement:

• .include ~/.volare/sky130A/libs.tech/ngspice/sky130.lib.spice tt

it worked fine in ngspice, but when I run it with lctime, I got an error that it cannot find the file ./~/.volare/sky130A/libs.tech/ngspice/sky130.lib.spice

I had to replace it like this, but then I would have my username in the path, which makes it unportable to other users:

.include "../../../../home/username/.volare/sky130A/libs.tech/ngspice/sky130.lib.spice" tt

I guess this should also be fixed inside KLayout?

This is most likely an issue in KLayout because lctime does not process the includes itself.

When trying myself I notice that the path needs to be quoted with "" as soon as it starts with a ~. Then I get the same error as you with a minimal example:

top.sp:

.include "~/include.sp"

~/include.sp: (empty file)

Minimal example for triggering the problem:

import klayout.db as db
n = db.Netlist()
n.read("top.sp", db.NetlistSpiceReader())

Yields:

Traceback (most recent call last):
 File "/home/user/lctime_issue4/lctime_issue4.py", line 4, in <module>
 n.read("top.sp", db.NetlistSpiceReader())
RuntimeError: Unable to open file: ./~/include.sp (errno=2) in top.sp, line 2 in Netlist.read

ngspice top.sp does not have a problem with that.
