A full description of the user interface is outside the scope of this manual. Instead, in this section, we provide a few pointers on how to go about finding how a particular feature works so that it can be altered or adapted.
In this topic:
When you press F7 or select the schematic popup menu Edit Value/Model the internal script 'value' is called. 'value' is a complicated script that identifies the type of component that is selected and performs an action appropriate for it. However the first thing this script does is find out if the component (or components) selected have a valuescript property. If it does then that script is called. This feature is used by all types of component developed since release 3 but some older devices are handled differently.
If you wish to modify the behaviour for a particular component type when F7 is pressed, first check to see if it has a valuescript property. If it has you can edit the script that it calls or change the property's value to call a different one. If it hasn't you can add such a property and provide a script for it.
There are two other properties associated with component values. These are incscript and decscript. These increment and decrement a components value when the shift-up and shift-down keys are pressed. Currently only the resistors, capacitor, inductor and potentiometer symbols use this property but you can add your own to any other symbol.
The SIMetrix user interface is implemented with about 550 internal (or built-in) scripts. These are built in to the executable file but can be bypassed so that their function can be changed. The code for all of these scripts can be found on the installation CD in directory script/builtin. The procedure for replacing an internal script is very straightforward. Simply place a script with the same name but with the extension .sxscr in the built-in script directory. The location of this directory is set in the file locations sheet of the options dialog box (menu File|Options|General...). On Windows this is usually <SIMetrix root>/support/biscript. SIMetrix always searches this directory first when executing an internal script.
