Hello Manthos

If I got you right, You need to measure the delay rise to rise and fall
to fall for 1000 bits, when there are several lines to measure (bus) and
then get the max min average etc.
Yes there is a way of doing that:
1. Make a .subckt the include all the measurements you need for one bit
in the bus. The subckt nodes like in and out will be the nodes to
measure (like probe contacts). you can use excel to make such a file.
2. Call the subckt as many times as needed for the bus bits.
3. cut the data from the .lis file to an excel spreadsheet and make your
analysis.

example:


.subckt meas_bit in out
.maesure tran bit_1 trig V(in)  Val=1.5 cross=1
+                   targ V(out) Val=1.5 cross=1
.maesure tran bit_2 trig V(in)  Val=1.5 cross=2
+                   targ V(out) Val=1.5 cross=2
.
.
.
.ends


xmeas_data_1  data_drv_1  data_rcv_1 meas_bit
xmeas_data_2  data_drv_1  data_rcv_2 meas_bit

In this example data_drv_1 is the driver of data 1 and data_rcv_1 is the
receiver of data 1.

Hope that help.
