IBIS users, I have a questions regarding simulation time for the V-T curves. I'm using the s2ibis3 script with spectre to create my model. When I used a simulation time of 3.0ns, I noticed that one of the rising waveforms was still settling under min. condition. As a result, I increased the simulation time. When I did so, the simulations ran to about 3ns still, then suddenly jumps to the final simulation time. All the following values revert to zero. I've included an example below. Has anyone seen this issue? If so, how do I resolve it? Thanks, April [Rising Waveform] R_fixture= 0.1500k V_fixture= 0.0 V_fixture_min= 0.0 V_fixture_max= 0.0 |time V(typ) V(min) V(max) | 0.0S 1.1973mV 0.9612mV 1.4062mV 50.51pS 1.2588mV 1.0489mV 1.4461mV 0.10nS 1.4906mV 1.2259mV 1.5095mV 0.15nS 1.9668mV 1.2757mV 1.8304mV 0.20nS 1.8327mV 1.2233mV 2.6068mV 0.25nS 1.6557mV 1.1725mV 2.5690mV 0.30nS 1.4814mV 1.1666mV 1.9088mV 0.35nS 0.8598mV 1.1546mV 1.0696mV 0.40nS 0.4808mV 0.9128mV 0.5701mV 0.45nS 0.3503mV 0.5327mV 0.4217mV 0.51nS 0.2508mV 0.3639mV 0.4082mV 0.56nS 0.1778mV 0.2484mV 0.4607mV 0.61nS 0.1280mV 0.2066mV 0.7377mV 0.66nS 0.1119mV 0.1626mV 0.8004mV 0.71nS 0.1326mV 0.1308mV -4.2468mV 0.76nS 79.3558uV 86.8717uV 40.2760mV 0.81nS 68.8351uV 55.0637uV 0.4070V 0.86nS 0.1283mV 11.4705uV 1.0312V 0.91nS -0.5143mV -17.7110uV 1.4799V 0.96nS -4.6066mV -52.9933uV 1.6007V 1.01nS -13.5297mV -87.7087uV 1.6237V 1.06nS 11.9615mV -0.1011mV 1.6280V 1.11nS 0.1830V -0.1240mV 1.6301V 1.16nS 0.4741V -0.1881mV 1.6306V 1.21nS 0.8229V -0.2977mV 1.6308V 1.26nS 1.1539V -0.4366mV 1.6314V 1.31nS 1.3391V -0.5495mV 1.6322V 1.36nS 1.4080V -0.6636mV 1.6325V 1.41nS 1.4325V -0.8265mV 1.6328V 1.46nS 1.4405V -1.0689mV 1.6329V 1.52nS 1.4472V -1.4895mV 1.6330V 1.57nS 1.4499V -3.2821mV 1.6331V 1.62nS 1.4511V -8.6506mV 1.6332V 1.67nS 1.4518V -17.2909mV 1.6333V 1.72nS 1.4521V -21.9207mV 1.6333V 1.77nS 1.4522V -25.7696mV 1.6334V 1.82nS 1.4522V -20.9140mV 1.6334V 1.87nS 1.4522V 20.9336mV 1.6334V 1.92nS 1.4523V 36.7265mV 1.6334V 1.97nS 1.4525V 0.1150V 1.6335V 2.02nS 1.4527V 0.1640V 1.6335V 2.07nS 1.4529V 0.2180V 1.6335V 2.12nS 1.4530V 0.2661V 1.6335V 2.17nS 1.4530V 0.3576V 1.6336V 2.22nS 1.4531V 0.4671V 1.6336V 2.27nS 1.4531V 0.5537V 1.6336V 2.32nS 1.4532V 0.6729V 1.6336V 2.37nS 1.4532V 0.8132V 1.6336V 2.42nS 1.4532V 0.9478V 1.6336V 2.47nS 1.4533V 1.0134V 1.6336V 2.53nS 1.4533V 1.0858V 1.6336V 2.58nS 1.4533V 1.1636V 1.6336V 2.63nS 1.4533V 1.1870V 1.6337V 2.68nS 1.4533V 1.2040V 1.6337V 2.73nS 1.4533V 1.2175V 1.6337V 2.78nS 1.4533V 1.2270V 1.6337V 2.83nS 1.4534V 1.2327V 1.6337V 2.88nS 1.4534V 1.2387V 1.6337V 2.93nS 1.4534V 1.2431V 1.6337V 5.00nS 1.4534V 1.2457V 1.6337V 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA 0.0S NA NA NA -- 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 Jun 22 12:08:58 2007
