Tech Lef missing SITE statements ?

marten over 11 years ago

Hi there,

we are usige SoC Encounter 13.13 with stm28lp Designkit. When we try to start floorplanning using:

floorPlan -site CORE -r 1 "$Utilisation" "$RING_WIDTH" "$RING_WIDTH" "$RING_WIDTH" "$RING_WIDTH"

Encounter throws: **ERROR: (ENCSYC-993): Cannot find site 'CORE'

So I checked the Technology Lef from our DesignKit

CadenceTechnoKit_cmos028_6U1x_2U2x_2T8x_LB@4.2.1/LEF/technology.16T.lef

and found out that there are no SITE Definitions inside. Do I have to add them manually ? Or do we need to request a new Tech Lef from CMP ?

Kind Regards

Unfortunatly the support for this special designkit has been stopped. So is there maybe another way ?
I am a bit confused, because all library LEF-Files reference a site called 'CORE12T'. So why is there no Site defined inside the TECH LEF ?

SITE definitions are typically in the MACRO LEF along with the macros that use that SITE. However, it's an easy thing to create the SITE definition. See the LEF/DEF Language Reference for the syntax.

Thanks Kari!
We got a new version of the designkit with correct LEF files.

Cheers,
Marten
