I need a help... Calibre PEX

[remind1104]

calibre pex manual

I'm using calibre tools for circuit design and layout.
DRC/LVS is OK. RC-extraction is something wrong.

I wanna use calibre pex to extract RC parasitics from my layout.
This is my procedure...

1. rule file setting(---.rcx)
2. inputs, outputs, PEX options setting by manual(I think it's no problem)
3. I correct rule file for including RC technology file
- add "include ~/rules
4. and Run PEX. but this error message is shown.
"Error while compling rules file ~/---.rcx:
Error INP7 on line 11 of ~/rules - incomplete keyword specification:
pex resistance"

So, I checked the RC tech file. INP7 on line 11 of the file is
"PEX RESISTANCE PARAMETERS metal6 TC1~~~"

Is that any problem in the RC technology file? Or my setting?
I don't understand this error message... Help me plz... tk

if you run lpe for rcc, you should include the r and c ext model.
suggest you do the cc fist, find the error.
please take care ground node. if you will use ldd devices, please check the subcirt for ldd

Re: calibre pex manual

I have some advices for you.
1: Open layout must be read only mode.
2:take care ground nod.
3:It is important that you are linking to the sth folder in your LVS run directory and not only to the run directory itself!
Hope you understand it.

Well this is just my experience - and since you di not provide any details...
In Calibre before PEX could be run you SHOULD match LVS. Then after you run LVS you can run PEX.
For starters do not change any switches in the PEX form.
The rule deck is in most of the cases the same as LVS. In LVS deck you probably find switches for extraction - i.e. #IFDEF RC_DECK or something cimilar.
That is the call to start RC extraction. The rules file is usualy used to define technology parameters for the extraction (sheet R capacitances etc)
But it is hard to figure out what is going on without the deck itself and more info.
Also - be careful with Calibre version - there are some commands which don't work anymore - check the version the deck is written for....
