Plot an internal node voltage after post-layout simulation

Hi,

I am using  Virtuoso ADE Assembler for post-layout simulation. And the version is ICADV12.3-64b.main.957.

My steps is following

1)I set "save all", ran post-layout sim (transient sim) and get the signal expression from result browser as below,

 v("/i0/Xith0/Xi0/Xthpsf_combo/Xampp/Xth_psf/Xth_sw[0]/Mpassgate2[0]:SRC" ?result "tran").

2) Put the expression in "Outputs Setup", changed Output Save setup back to "Select". Reran the post-layout sim.

It showed "eval err" for that plot. 

The expression of the internal node seems different from the normal output expression

The circuit is big and I will run the simulation with parameter sweep, so I want to set Output Save as "Select" to save hard disk space. 

What should I do to plot the internal node signal in post-layout sim?

Thanks and regards,

Yutao
