Hi All, As attachment is huge, sending data again which I have simulated for bias voltage versus capacitance. param_dcbias C_comp temperature 0. 2.880e-12 85.0000 0.2000 2.937e-12 85.0000 0.4000 2.880e-12 85.0000 0.6000 2.837e-12 85.0000 0.8000 2.768e-12 85.0000 1.0000 2.600e-12 85.0000 1.2000 2.343e-12 85.0000 1.4000 1.902e-12 85.0000 1.6000 1.922e-12 85.0000 1.8000 1.960e-12 85.0000 Please let me know which value I should use in my IBIS model. Regards, Girija/Amitava From: Girija V Chougala Sent: Wednesday, June 26, 2013 2:15 PM To: ibis-users@eda.org Cc: Amitava Banerjee Subject: Query on Ccomp parameter for IBIS model Hi, I have worked on deriving C_comp value for an I/O buffer (used the same technique given in IBIS cookbook - http://www.vhdl.org/ibis/cookbook/cookbook-v4.pdf ). The Vcc of the device is 1.8V. I have simulated C_comp for different bias voltages (VDC) - 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 1.8. The different C_comp values obtained are given in the attached bmp file. Please let me know which value should I use in my IBIS model.
