最近仿真时遇到一个问题,提示要修改“max_minstep_nonconv”,最后研究了很久才找到了一种解决方案,特此记录分享之。
问题描述:
(SPECTRE-16927): Transient simulation reaches maximum allowed number of convergence failures below minstep within 5% of stop time.
Change option `max_minstep_nonconv' to adjust the allowed maximum number of convergence failures below minstep.
解决方案:
在ADE 窗口中,找到 Simulation/Options/Analog/Miscellaneous, 然后在Additional arguments中添加max_minstep_nonconv=500 这样一串字符
