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.

Click to expand... Perhaps; just try it! Or try this: Code: .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'
