#113108 - We had 'em with HILO in '86 Responding to: ???'s previous message |
IIRC, it was HILO under HPUX that provided the ability to model microprocessors, given a proper model, with output spec's and input spec's for each pin on the microprocessor, MCU, DAC, or ADC. Even a few mixers models were available along with the usual complement of BJT and FET types then available. PSpice always supported PLD's and allowed you to create your own models based on templates they provided. From that it wasn't a long reach to a model of an MCU, though geting one "certified" by a mfg was nearly impossible.
Spice allows the logic to be modeled behaviorally while the inputs and outputs are modelled as analog functions. There are pretty standard models for the totem-pole and tristate models applicable to most MCU's, though functions like PLL's, crystal oscillators, and of course, the crystals, are a mite more device specific. It's a pretty tedious job modelling a PLD. I can't see myself doing it for an 8052 unless someone has really deep pockets. RE |
