Title: Ultrasim syntax for probing current at particular nodes
Post by ranjang on Sep 18^th, 2014, 5:55am

Hi,
My requirement is to probe current at particular nodes for verification purpose.I am using ultrasim simulator and running simulation with irun -amsf option

I am writing like this in acf.scs file where I give complete path for the port where I want current.
.probe i(top_tb.u_k0_wrapper.u_pr1.u_ana_core.u_k1.u_k2.u_k3.u_k4.ildo1.IBIAS)

I don't see the current probing and it gives some warning

Cannot find element 'IBIAS' because it is missing
or it was cut in circuit 'subckt_name' during the
simulation.

Hi,

Please see below:

1. Create a probe.tcl file. In that file, you have to use "-flow" option as shown below:

probe -create -flow -shm -ports top_tb.u_k0_wrapper.u_pr1.u_ana_core.u_k1.u_k2.u_k3.u_k4.ildo1.IBIAS

2. Parse the file in the irun option with -input option

Hope this helps.
Thank you.
