Its integrated text editor created circuit descriptions for a simple, linear, analog simulator.
2.
From 1968-1972 analog simulators.
3.
In the same time frame Cadence initiated the creation of Verilog-A to put standards support behind its analog simulator Spectre.
4.
The most well known analog simulator is SPICE . Probably the best known digital simulators are those based on Verilog and VHDL.
5.
The analog simulator is a command line program which is run by the GUI in order to simulate the schematic which you previously setup.
6.
Commercial and industrial analog simulators ( such as SPICE ) have added many other device models as technology advanced and earlier models became inaccurate.
