TPDDD<br />

TPDDD<br />

Eldo built-in waveform function<br />

Returns the propagation delay with wv_in1 and wv_in2 both falling.<br />

Usage<br />

set out_value [tpddd $wv_in1 $wv_in2]<br />

set out_value [tpddd $wv_in1 $wv_in2 $vth]<br />

set out_value [tpddd $wv_in1 $wv_in2 $vthin $vthout]<br />

set out_value [tpddd $wv_in1 $wv_in2 $vthin $vthout $before $after]<br />

set out_value [tpddd $wv_in1 $wv_in2 $vthin $vthout $before $after $occur]<br />

Arguments<br />

Note<br />

For a complete description of TPDDD and its parameters, see the .EXTRACT command in<br />

the Eldo Reference Manual.<br />

• wv_in1<br />

The first input waveform the function is acting upon.<br />

• wv_in2<br />

The second input waveform the function is acting upon.<br />

• vth<br />

Voltage defining a threshold or starting point.<br />

• vthin<br />

Voltage defining a threshold or starting point.<br />

• vthout<br />

Voltage defining a threshold or starting point.<br />

• before<br />

Causes the function to be performed only if TIME < val.<br />

• after<br />

Causes the function to be performed only if TIME < val.<br />

• occur<br />

Computes the function for the VALth occurrence of the event.<br />

Return Values<br />

out_value is the propagation delay.<br />
