Status of HICUM integration in circuit simulators HICUM users meeting in Monterey September 2002

Sophie Lavenir – Hicum Report 08/05/2019 Basic tests : 2 different sets of parameters, one with self heating. 3 test benches for each set of parameters at 27 and 150ºC: Forward Gummel simulation + sweep at Vbc [-0.5V,1.5V,0.5V]. Ic vs. Vce characteristic at Ib=cst. (Ib [0.1u,10.1u,1u]) fT vs. Vbe characteristic. The comparisons are made with Device, Pr. Schroter’s simulator. The tested simulators are : Eldo, Spectre, Aplac, Hspice and ADS. => ST Target : less than 0.1% difference. May-19 Sophie Lavenir – Hicum Report

Ft plot : problem with Hspice The results presented in the following slides are imprecise. Precisions on the ft test : The instantiation of an input and an output port is required. Until 0.5% of error for a S param. in dB between Hspice and the other simulators for a circuit composed of passive elements only. Problem of port instantiation reported to Synopsys.

Sophie Lavenir – Hicum Report Comparison Sum-up Simulator Tested version Comments + improvement since june 2002 report Eldo 5.8 Good results in DC + ft. Spectre IC446 MSR7 Good results in DC. (improvement at 150ºC) Discrepancies for the ft simulation with self-heating. Aplac 7.70d Still too big discrepancies especially at 150ºC and with self-heating. (little improvement at low Vbe) Hspice 2002_2_1 Good results in DC (very big improvement + good implementation of self-heating). Discrepancies for the ft simulation, see also the problem of port instantiation. ADS 2002.C No improvement since previous version. Still discrepancies + big problems at 150ºC and with self-heating.
