hello....
i have heard about different types of SPICE software..which is basically used for circuit simulation...
now what is the difference between pSPICE,NGSPICE, and the spice which is used in ORCAD...?
please help if u have any idea....
thanks...
Orcad PSpice and HSPICE are the most popular commercial SPICE derivatives
Circuit simulation programs like Multisim or Proteus are also using SPICE compatible circuit netlists and basically a SPICE-like simulation core
LTspice is a popular SPICE version freely distributed by Linear Technologies
Texas Instruments ships a restricted version of TINA (another comercial SPICE derivative) for free.
Most SPICE based simulators are keeping the netlist and circuit element syntax of the original version, which particularly important when importing models. They also have mostly incompatible extensions to the basic SPICE functionality. Many versions are adding schematic entry, which is incompatible by nature due to different file formats.
