Title: Creating Symbol from VerilogA view
Post by rajdeep on Apr 18^th, 2007, 11:46pm

Hi all,

I was trying to create symbol view of a cell from its VerilogA view.
When I do it manually, I just open the VerilogA file from the library maanger. Make some modification
and close the editor by using :wq ( I use a vi editor). A dialogue Box pops up. I press YES,, a FORM pops up.
I just press OK, and a window opens with the symbol created.

I want to replicate the above steps using SKILL commands. I use the following commands in the order given below:

editor="touch"
ddsServOpen("lp3918_13nep108_rajdeep_VAmodels" "testbus_cell_baba" "veriloga" "edit")
hiDBoxOK(_schDBox)
hiFormDone(hiGetCurrentForm())
hiCloseWindow(getCurrentWindow())
editor="xterm -e vim"

But it does not work. The problem is due to the command, coloured red. I thought this will do the same thing as pressing YES
in the dialogue box, that pops up after I quit the editor. In the next two commands I have used functions which return current forms and current window. But, I could not find the same for a dialogue box. Is there any such command?

Any other set of functions that can create a symbol from a Veriloga view will also do for me.

Plz help!

See my other responses on this - no point in me repeating myself.

I've found the solution..these are the funcions/commands to be used sequentially.

schHiViewToView("lp3918_13nep108_rajdeep_VAmodels" "testbus_cell" "veriloga" "symbol" "Composer-Symbol")
hiFormDone(hiGetCurrentForm())
hiCloseWindow(getCurrentWindow())

The only problem is that the final window containing the symbol remains open!!!
But hiCloseWindow(getCurrentWindow()) should have closed the window!!! :-?

What can be the reason??

Well, if you'd used schViewToView (not schHiViewToView) the UI and so on would not have opened, I think.

The close window didn't fire because something was not blocking, and probably the window was not open yet. Something like that.

How can I make this work like a sequential program? When the comand hiFormDone(hiGetCurrentForm()) was executed, the window
opened. If the next command hiCloseWindow(getCurrentWindow()) runs after this, we can close the window. As you said, the problem is
that the command is getting executed before the target window is opened.
Is there any way to make this skill fucntions run sequentially i,e the next command can only get executed after the previous commands' results are all evaluated?

Yes, don't use the "HI" version of the commands. (I suggested this previously - use the schViewToView function instead).
