Hi Experts, Could you please answer my below questions? 1. If vdiff value varies for diff pins (due to diff modes of operation, namely speed), How do I define that in IBIS models. Through [Diff Pin] keyword, we can pass only one value to vdiff. 2. How to define common mode value in the diff signals? (I believe there are other IBIS users who raised the same question some time earlier) 3. When measuring C-Comp for drivers, I see three main variables on which die cap depends on. 1. Freq of operation 2. Data value (0 to vdd) to be sent 3. Process corners I vary these three variables and finding the max and min value for C_comp. Is that right? But, I usually see very huge die-cap for the drivers(unrealistic) -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean. -------------------------------------------------------------------- |For help or to subscribe/unsubscribe, e-mail majordomo@eda-stds.org |with the appropriate command message(s) in the body: | | help | subscribe ibis <optional e-mail address, if different> | subscribe ibis-users <optional e-mail address, if different> | unsubscribe ibis <optional e-mail address, if different> | unsubscribe ibis-users <optional e-mail address, if different> | |or e-mail a request to ibis-request@eda-stds.org. | |IBIS reflector archives exist under: | | http://www.eda-stds.org/pub/ibis/email_archive/ Recent | http://www.eda-stds.org/pub/ibis/users_archive/ Recent | http://www.eda-stds.org/pub/ibis/email/ E-mail since 1993Received on Fri Feb 2 02:34:44 2007
