vkim Posted May 26, 2021 Share Posted May 26, 2021 Hi all, I'm looking for an IBIS model or some sort of simulation model for the JTAG-SMT2. Please let me know if there is one available or something that I can use/reference for my SI simulations. Thanks! Link to comment Share on other sites More sharing options...
0 JColvin Posted May 27, 2021 Share Posted May 27, 2021 Hi @vkim, Unfortunately, Digilent does not have any simulation models for the JTAG-SMT2 or our other JTAG modules. Thanks, JColvin Link to comment Share on other sites More sharing options...
0 CHONG Posted March 3, 2022 Share Posted March 3, 2022 Since you provide neither the IBIS model nor the schematic for the JTAG-SMT2, can you describe the output driver configuration, like the source termination value if any and the trace length between the output driver and the SMT connector. In addition, I would like to know the current strength as well as the rise and fall time of the driver. These technical information should have been included in the datasheet. So, do you even have a technical datasheet for the JTAG-SMT2? Link to comment Share on other sites More sharing options...
0 JColvin Posted March 4, 2022 Share Posted March 4, 2022 Hi @CHONG, I got some answers to your questions: Output driver configuration -- push-pull drivers source termination value -- No source termination Trace length between the output driver and SMT connector: Signal length [mm] TMSC 8.869848481 TDOC 24.731727984 TDIC 12.526955262 TCKC 5.510660172 current strength -- the signals are 24 mA drivers rise and fall time -- we do not have this characterized Thanks, JColvin CHONG 1 Link to comment Share on other sites More sharing options...
0 CHONG Posted March 7, 2022 Share Posted March 7, 2022 Thanks! But the rise/fall time need to be characterized. If not, specify what device is or close to it Link to comment Share on other sites More sharing options...
0 JColvin Posted March 7, 2022 Share Posted March 7, 2022 Hi @CHONG, We do not have the characterizations, though I was provided the names of the onsemi ICs that each signal is driven from/goes into. Quote TCKC and TDIC are driven by NC7WZ126, TMSC is driven by NC7SZ126. TDOC goes into NC7SZ157 Thanks, JColvin Link to comment Share on other sites More sharing options...
0 CHONG Posted March 16, 2022 Share Posted March 16, 2022 Excellent! Thanks for clearing things up - appreciate it . Link to comment Share on other sites More sharing options...
