LTspice Question
LTspice Question:
I have a client using LTspice. What is the best way for him to import a design from PSpice? Would it work if I make my schematic into a SUBCKT that includes the device models within the subcircuit? ...Jim Thompson -- | James E.Thompson, P.E. | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona Voice:(480)460-2350 | | | E-mail Address at Website Fax:(480)460-2142 | Brass Rat | | http://www.analog-innovations.com | 1962 | America: Land of the Free, Because of the Brave |

LTspice is very compatible to PSPICE except for digital devices. Why making a subcircuit? Just run the netlist as it is. Best regards, Helmut |
