Error about Environment Variable settings

Haven't you answered your own question? It sounds as if it's expecting the UNIX $GF_PDK_HOME to be set to the location of the PDK (I assume). Because that's not set, the SKILL variable gfPdkHome is nil, which results in all those SKILL errors.

Andrew.

Hello Andrew,

Thank you for your prompt response.  I have set the environment variable and still coming up with an error.

I have attached my .cdsinit and the new error screen shot.

Thank you always for your help.my_cdsinit.docx

Well I might be wrong but in your .cdsinit it says:

if(gfPdkHome = getShellEnvVar("/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/")

...shouldn't that be getShellEnvVar("GF_PDK_HOME")

Looks to me like you were confusing variable name and value.
And what do you get when you type  getShellEnvVar("GF_PDK_HOME")  in the CIW ?

I get nil.

I am not familar with the skill language. 

I suspect you modified the .cdsinit file and changed the getShellEnvVar() line to have the full path rather than "GF_PDK_HOME". I think you may also have set the line that follows it - the strcat.

If it had getShellVarVar("GF_PDK_HOME") in the .cdsinit code, you would have needed to do:

setenv GF_PDK_HOME /path/to/wherever

or 

export GF_PDK_HOME=/path/to/wherever

(first is for csh, second for ksh/bash) before you started virtuoso.

Then the getShellEnvVar would get the path from the UNIX environment variable.

Regards,

Andrew.

well - it means the GF_PDK_HOME env variable is not set which is exactly your problem.
Try:

setShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/")

I am using bash and I am still getting the same error. export GF_PDK_HOME=/GLF8HP/130HPSIGE-8HP/V1.8_1.1HP/ and i am putting it above the if statement and still getting the same error. What do you adsvise?

Thanks a lot.

export GF_PDK_HOME=/path/to/wherever

What Andrew meant is to set it on the Unix shell - before you launch virtuoso. That way the env variable is then inherited by virtuoso. The setShellEnvVar is a SKILL command which you need to put in your .cdsinit.
What I don't understand is that after the export command in the bash you don't see that env variable in virtuoso. You do the export GF...=...  before you launch virtuoso don't you?

I want to put the envirnonemt variable in my .cdsinit file. I did:

setShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/")

And in CIW when do:   getShellEnvVar("GF_PDK_HOME") It still comes back nil

I am getting the same error messages as before. I don't know what I am doing wrong.

Thank you so much. I am attaching the copy of my .cdsinit file again.

Please pay careful attention to what we're saying. You changed the first line to:

if(gfPdkHome = getShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/") then

You're mixing the setShellEnvVar with getShellEnvVar - the getShellEnvVar call you've specified makes no sense.

This should be:

if(gfPdkHome = getShellEnvVar("GF_PDK_HOME") then

I suggest you either set GF_PDK_HOME before you start virtuoso as mentioned before, or add another line before the lines above:

setShellEnvVar("GF_PDK_HOME=/home/grps/ef-test/GLF8HP/130HPSIGE-8HP/")

That will set it, and then the getShellEnvVar("GF_PDK_HOME") will get the variable value.

Andrew
