I have a script (http://www.cadence.com/Community/forums/p/24288/1317148.aspx#1317148) that will save the design tree file to a shell to run a shell script on, working in Virtuoso v5, but is breaking in Virtuoso v6 on the command hiSaveAsViewFile.
The Save File As form looks quite different in v6, but I cannot figure out Cadence's documentation to search for (anything..) something like this.
In v5 I use:
hiSaveAsViewfile->file->value-> = Newfilename
However, in v6, I get the error message " eval: unbound variable - hiSaveAsViewfile".
Since testing with print statements is able to show me that the variable Newfilename is properly defined, and the command hiSaveAsViewfile() works in v6, I can only guess that the form itself is different in v6, and the format hiSaveAsViewfile->file->value is not the same.
2 Questions -
1. how can I test for the version of Virtuoso as an environment variable so I can handle this save function accordingly?
2. what is the v6 format for hiSaveAsViewfile->file->value??
many thanks in advance!
The form looks like it is probably a QT form and won't have the Skill hooks to it. However, you can simply save it to a file like this:
hiSaveAsViewfile( [w_windowId] [t_fileName] )
In 6.1: dbGetDatabaseType() -> "OpenAccess"
In 5.1: dbGetDatabaseType() -> "CDBA"
In reply to dmay:
I have the file saved out successfully now and will try this same code in v5.
I get an error when I try to test the environment for version using your suggested code however.
In reply to jaleco:
What error do you get in your CIW, and what exactly did you try for your Skill code? The command is just: dbGetDatabaseType()
Don't add the "->" stuff, I was just trying to show you the output of the command. If you are running a really old version of Cadence 5, the command might not be available, in which case you might need to do something like this:
procedure(myCheckIsOA() if(getd('dbGetDatabaseType) && dbGetDatabaseType() == "OpenAccess" t nil )) ;proc
Hello Derek, or others who may see this thread,
I am running the script below to operate on the Design Tree saved out to the shell as an ascii file, but the hiSaveAsViewFile() cmd does not overwrite an existing file.
Is there a way to force hiSaveAsViewFile() to overwrite an existing file?
If not, I can always do it with a shell script, but using SKILL would be simpler.
Any help with this would be much appreciated!!!

Use the hiSaveViewfile() function instead, it has a third optional argument g_donotOverwrite that you can set to nil in this case. This function appears to exist in both IC5141 and IC61x versions.
