hi all, I am trying to generate .lib for the standard configuration of sense amplifier using encounter library characterizer. but following error appears after db_prepare -f commnad:
==============================
DESIGN : CHAPPEL_CKT
==============================
- analog node : NMOS_DRAIN
- removed pull-up transistor (1) from VOUT_RIGHT
- loop node ( VOUT_LEFT ) is found
=> no simulation
================================
stimulus generation summary
================================
Name #MOS #DVEC #RVEC
----------------------------------------
CHAPPEL_CKT 5 0 0 *
----------------------------------------
0 0
Reading setup file : /home/opensilicon/demo2/demo_jun11_2/demo/setup.setup
[ERROR(db_prepare)] can not match default LOAD for PIN : $DEFAULT_PINS$
Any suggestions?
