Stimulus PartsPulse (pulse)Pulse (pulse)This part generates a simple scalar output pulse waveform or a pulsewaveform with multiple clock edges.You can specify a label for the generated VHDL process (or Verilog initialblock). If not specified, a unique label is generated from the part name (forexample, pulse1, pulse2..pulseN).You can specify any number of clock edge times by entering a commaseparated list in ascending order. The default pulses have a rising edge but you can set the invertoption to generate falling edge pulses.You can specify the initial value of the pulse (0, 1, X or Z) before the timing offset and theoffset time (which must be less than 1 second) before the pulse generator starts.Time intervals can optionally be specified in milliseconds (ms), microseconds (us),nanoseconds (ns) or picoseconds (ps). Seconds are assumed if no unit is specified. Spaces areautomatically used between the time value and unit in the generated HDL.Frequencies can be specified in kilohertz (kHz), megahertz (MHz), gigahertz (GHz) or terahertz(THz). If no units are specified, hertz are assumed.266ModuleWare Reference Manual, Library Version 1.9September 18, 2008
