How to use another signal as TRIG or TARG value in HSPICE .MEASURE

[zb8521]

Hi,

I would like to measure the delay from rising of one signal to the crossing of another two signals, anyone know how to do this? Can I use something like:

.MEASURE TRAN delay TRIG v(sig_1) VAL='vdd/2' RISE=1 TARG v(sig_2) VAL=v(sig_3) CROSS=1

Is the using of v(sig_3) legal here as VAL?

Thanks.

.MEASURE TRAN delay TRIG v(sig_1) VAL='vdd/2' RISE=1 TARG v(sig_2) VAL=v(sig_3) CROSS=1

Is the using of v(sig_3) legal here as VAL?

Perhaps; just try it! Or try this:

.MEASURE TRAN tcross WHEN v(sig_2) = v(sig_3) CROSS=1
.MEASURE TRAN delay FROM v(sig_1) VAL='vdd/2' RISE=1 TO='tcross'
