I'm not sure why it would have a 0.8V steady output from the description you've given - maybe showing the netlist would help? However, it's certainly not going to work properly - feeding a 1ns period...

Hello Andrew, As shown in your example too,Why does the OPAMP (in the /op node) switches between 0.3V and 0.85V? Its suppose to go from 1.2 till 0. Thanks

Hai dave It shows only fully filled vias in the pad but i need to show if it liitle bit touched in the pad that also need to show.
View ArticleForum Post: RE: ideal op amp comparator settings
Why would you set it (vsoft) to 10V below the supply rails? That's clearly not going to work (clear if you read the model). In fact, why don't you just use a comparator model (there's one in ahdlLib...
