Hi, Our group is setting up the updated version of IBM CMOS9RF (released at the end of last month). The tools we are using are: Cadence 5.1 and Calibre v2006.4_35.37. The problem we encounter is at calibre PEX. It reports error of "Error while compiling rules file __cms9flp_5_01_00_01LD.xrc.cal__: Error INP7 on line 201 of <install path>/IBM_PDK/cms9flp/V1.3.0.0IBM/ Calibre/xRC_new/cms9flp_5_01_00_ 01LD.xrc.cal - incomplete keyword specficiation: unit" I wondered if we had to use the latest Calibre v2007.2_34.22? You think the problem is due to the old version of Calibre we are using? Thank you very much.
