The evaluation versions of MicroSim Schematics and MicroSim PSpice A/D allow you to set up circuits and simulations for analog, digital, and mixed analog/digital designs. These device limitations apply: - 64 analog nodes - or, 10 transistors (any combinationn of B, M, Q, or J devices) - or, 2 opamps - or, 10 transmission lines (up to 4 coupled) - or, 65 digital primitive devices - or, logic output transitions limited to 10000 - or, logic expression primitives limited to 36 I/O pins - or, any combination of the above (which will result in a lower allowable number of each)
