This tutorial explains how to import Orcad .DSN files in NI Multisim, and what can be imported.
NI Multisim has basic capability for importing OrCAD .DSN files. The following is the extent of the file import support. The support is limited to schematic capture designs only; no simulation models or data can or will be imported. However, if you would like to simulate an existing PSpice (or other) netlist within Multisim, please consult the technical article on Importing a SPICE Netlist for Simulation in NI Multisim.
