Title: Assura RCX fails with Generic PDK 45nm
Post by kmmankad on Mar 5th, 2013, 10:07am

Hey all,
I'm using the Generic PDK 45nm 3.5 (gpdk045_v_3_5) for my designs.I have created a layout,which passes DRC,and LVS.I want to create the Analog Extracted view for my layout.

I am using Assura RCX(not qrc,since I dont have it.) for this.However,it always fails with the following output log file:

Constructing the RCX run script
Could not open file /Cadence/IC614/GPDK45/assura/RCXspiceINIT for reading
*WARNING* Bad return status from RCX script generator. 0x100

The RCXspiceINIT file simply hasnt been created at all in that path.

Some solutions on other forums suggested changing the read/write permissions of my gpdk045/assura folder,but even that hasnt helped.

I'm making a standard cell library,and so the analog extracted view is very important for me.

Please guide me.

Thanks,
kmmankad

Assura RCX can not find your device library to map the devices into the extracted view.
This might be because it has no access to your cds.lib file or did not find it.
Check your settings regarding this point.
