So I'm still a newbie at CL and putting it through some paces. Some funny things have started to happen, this circuit just started to simulate in transient analysis brutally slow. Meaning I was being asked by the browser to kill the pages because of non-response. I noticed just after this (maybe coincidentally) that my Sophos antivirus software was blinking about quarantining 3 items which I didn't recognize claiming them as adware. Is CL installing adware? Is there anything about this circuit that would take >1000 seconds to simulate (trans for 2mS @ 100nS steps)?
