Copyright ©c 2007 Mike BrinsonIntroduction Title
DC and independent voltage pulse generator test.Test file name SPICE specification
Format: VX N+ N- [[DC] DC/TRAN VALUE] [AC [ACMAG [ACPHASE]]] Notes: 1. Characters [ and ] enclose optional items 2. Character / denotes OR 3. Independent voltage source names begin with the letter V 4. X denotes name of source 5. N+ and N- are the positive and negative nodes respectively 6. Voltage sources need not be grounded Specification of SPICE statement being tested: VX N+ N- [[DC] VALUE] [PULSE(V1 V2 [ TD [ TR [ TF [ PW [PER]]]]]] Notes: 1. PULSE generates a periodic pulse, where 2. V1 is the initial value; default: must be specified 3. V2 is the pulsed value; default: must be specified 4. TD is the delay time; default value = TSTEP 5. TR is the rise time; default value = TSTEP 6. TF is the fall time; default value = TSTEP 7. PW is the pulse width; default value = TSTOP 8. PER is the period; default value = TSTOP,Test code and schematic
