Spicy Schematics - ischematics.com A comparison of time-domain S-parameters of a RG58 cable computed by different
methods including Theory, CST simulator , SPICE (MC10) and DWS simulators. The good agreement among methods is shown
as well as DWS advantages for fast modeling and simulations of lossy lines using both circuital, BTM and hybrid methods.

Congratulations Spicy, we now hit 200 FB likes! Thanks everyone ... remember if you like Spicy, please help
by posting a good review on itunes .. it helps us support development of the app .. we have only a handful
of reviews and most of the time from the few who wanted something else and were not happy ... but 200
FB likes means maybe we can get 200 good reviews on itunes! That would help us out a lot ... just go to
itunes, search ischematics.com, and you can review the free, or full or now swan versions, which ever you
like .. (or review all if you like) ...

Spicy has updated our web version (ipad will follow soon) to have a new simple method for making wires ..
just click the wire button, then click and drag your wire .. when you lift up its done ... it also will start at the
nearest part pin automatically to help you out! ... this is as it should have been done, and we know a few
users have asked for this, so try it out on the web today, and we will roll it out on ipad soon!

This video shows an actual comparison between a commercial simulator (MC10) and SpicySWAN during the
simultaneous simulation of the same circuit 10_LC_TL. To get similar accuracy levels, both sims are carried
out the same time step of 10 femtoseconds on a time window of 0-50ns.
MC10 runs locally on a quad core I7 PC. SpicySWAN sim is carried out by SWAN/DWS engine running on a
SpicySWAN server in the Web.
