Does anyone know what the difference is between an Intel Dual-Core and the Core 2 Duo? Is one 32bit and the other 64?

This here machine has a dual core and it really shows up as two separate CPUs in the control panel.
Actually, it seems to be power dissipation.
In that respect I was positively surprised. Did a few >1/2h heavy duty SPICE sims lately and the CPU fan barely picked up speed. It's very quiet.
1/2 hour is NOT "heavy-duty" ;-)

Ok, it's not like your chip designs. Just came across a puzzler. A circuit works on the screen, puts out lots of energy but doesn't consume any. I can set the voltage source series resistance to 1M or whatever and nothing changes. Hey, I might really be on to something here, solving global warming and all that.

Guess I'll waltz over to the lab and hit that red button on the Weller. I do not trust sims all that much.
Probably have an extra source in there somewhere, or you AC source is
providing the power. There are no such things as "puzzlers", just
cockpit errors ;-)

No other sources except one low voltage to the small stuff. It cannot generate the levels coming out. Yeah, it might be a cockpit error but there is nothing obvious and mostly it's faster to lash up something in the lab.

The only time that's a pain is when it entails waiting for a Digikey order to arrive. Then I tell the shepherd to "keep a good watch". She immediately understands and moves over to a place where she can see the road, then almost explodes when the Fedex truck comes around the corner. This avoids a packages sitting there at the entrance without me knowing it has arrived.

Spice's "initial conditions" can store a lot of energy!

Spice is not the do-all solve-all of the world. ...


Certainly not in the analog high-power world. For RF small signal stuff it's pretty good though.


... It takes some realism
from the cockpit to get useful results.


I thought 100K in series with the lone source would be enough realism. Shoulda killed it but didn't :-)

With some apps the time spent on models can be much longer than actually building stuff in the lab. As long as the parts from Thief River Falls arrive in due course.
