*Error* eval: undefined function – hiGraphicMode

You didn't give much to go on - for example, what exactly you were doing when the error occurred, and where it was reported.

My guess is you're running some background program which is failing because there's a call to hiGraphicMode in the libInit.il of a library - this would be solved typically by ensuring the code does:

when(isCallable('hiGraphicMode)
  ... the code which calls hiGraphicMode()
)

But hard to be more precise without some better pointers.

Hi Andrew,

When I ran LVS, LVS failed and reported an incorrect connection. And I saw that error in CIW.

Posting more (or all) of the CDS.log would probably help - it would give some context as to what you're doing.

Regards,

Andrew.

Thank Andrew,

Here is the CDS.log when I run LVS:

OK, given that the messages are coming from stream out and CDL netlisting (both of which happen in background, at least by default, and probably in the Calibre LVS interface), it appears likely that it is indeed something in the libInit.il of the technology library. Can you check?

Regards,

Andrew.

Hi Andrew,

I have seen libInit.il file in technology library. I found this code:

attFile = strcat(ddGetObj("<tech>")~>readPath "/deviceStatTable.il")

 if( isFile( attFile ) then

   load(attFile)

   printf("<Vendor> PDK <tech> Device Status Table loaded. \n \n")

 else

   warn("Device Status Table for IBM PDK not found and thus not loaded.")

 );if

 ; Only for IC6 / Open Access in graphic mode : Set correct via dimensions

 when(and(getd('dbGetDatabaseType) dbGetDatabaseType()=="OpenAccess")  && hiGraphicMode()

   envSetVal("layout" "wireViaParamCalcMode" 'cyclic "viaDefDefaults")

 );when 

 Up to blue lines, I think it is correct because I saw the line <Vendor> PDK <tech> Device Status Table loaded. was printed in CIW. I have 2 questions:

(1) What is the function of function hiGraphicMode()

(2) How can I fix the error?

Thank you so much. 

1. This command tells Cadence if it is running in graphics mode or not. It is probably not defined when running streamout or lef/def.

2. Try checking to see if the function is defined:

 when(and(getd('dbGetDatabaseType) dbGetDatabaseType()=="OpenAccess")  && and(getd('hiGraphicMode) hiGraphicMode())

   envSetVal("layout" "wireViaParamCalcMode" 'cyclic "viaDefDefaults")

 );when 

Derek

Thanks Derek for answering. 

A small suggestion. In this case it won't make any difference, but I would suggest using isCallable('funcName) rather than getd('funcName) in such checks. getd tells you whether the function is defined already, whereas isCallable tells you whether it is defined or whether it would be defined once auto loaded (ie if it is autoloadable). That's a better test because sometimes the function you're testing for is in a context which has not yet been loaded but would be loaded if you called the function.

Kind Regards,

Andrew 

Thank Derek and Andrew,

After I edit the libInit.il, the error disappears. However, I would like to ask for you guys check the report for me, please.

I would like to ask one more question. I created 2 cells for test, one cell have LVS clean, the other one is not.

When I ran LVS in the cell which has LVS clean, *Error* eval: undefined function – hiGraphicMode did not occur. The Calibre RVE displayed the same result when getd(‘hiGraphicMode) or isCallable(‘hiGraphicMode) were used, i.e LVS is correct.

When I ran LVS in the cell which has LVS not machted, Calibre LVS still generated the RVE result, i.e LVS is incorrect (missing port), even though the *Error* eval: undefined function – hiGraphicMode occurred. After getd(‘hiGraphicMode) or isCallable(‘hiGraphicMode) functions were used, The Calibre RVE displays the same result: incorrect (missing port).

So, I wonder that did I setup correct environments?

 As I mentioned, in this case it won't matter whether you use getd or isCallable (because hiGraphicMode will be defined (or not) as soon as the application starts).

The LVS error is almost certainly nothing to do with this error - all that would result in is that it doesn't set a particular cdsenv setting - and that wouldn't affect LVS. So the error was non-critical in this case.

So your LVS error is simply that you have an LVS error - a missing port. You'll have to debug that as usual (and as it's a Calibre error, I can't really help you, since it's not a Cadence product and I only have limited Mentor Calibre experience).

Regards,

Andrew.
