To determine the part name for an equivalent current source ➡ In the table of voltage source parts, replace the first V in the part name with I. For example, the current source equivalent to VDC is IDC, to VAC is IAC, to VEXP is IEXP, and so on. Using VSTIM and ISTIM You can use VSTIM and ISTIM parts to define any kind of time-based input signal. To specify the input signal itself, you need to use the Stimulus Editor. See The Stimulus Editor utility on page 535. 2. VPWL_F_RE_FOREVER and VPWL_F_N_TIMES are file-based parts; the stimulus specification is saved in a file and adheres to PSpice netlist syntax. Tip You can edit value_expr property of a VPWL_abm part to specify your own expression. This part also allows you to produce messages for threshold violations. Edit warn_cond to specify a warning condition and specify the message to be displayed on the condition in the warn_message property. Similarly, you can add an error condition and message by setting the error_cond_expr and error_message properties. Note: You can add more than one value-pairs to a part by updating the PSPICETEMPLATES property of the part. For example, to add the property FOURTH_NPAIRS: V^@REFDES %+ %- ?DC|DC @DC| ?AC|AC @AC| PWL ?TSF|TIME_SCALE_FACTOR=@TSF| ?VSF|VALUE_SCALE_FACTOR=@VSF| \n+ REPEAT FOREVER \n+ @FIRST_NPAIRS ?SECOND_NPAIRS|\n+ @SECOND_NPAIRS ?THIRD_NPAIRS/\n+ @THIRD_NPAIRS/| ?FOURTH_NPAIRS/\n+ @FOURTH_NPAIRS/ ENDREPEAT
