Original question:

PSPICE-FOR-TI:Cannot connect to Cadence license service(LMC-07712)

PSPICE-FOR-TI: Cadence license server's IP address is incorrect

Floyd Xu

Part Number: PSPICE-FOR-TI

Tool/software:

The IP adress of the license server of PSPICE FOR TI is incorrect.

As the related thread metioned, the PSPICE FOR TI's hostname is: cdsplicwc.cadence.com.co.ltd, and the correct corresponding ip address shall be: 64.207.220.106

But unfortunately ,  I have tried all computers I have, and the DNS server returned the IP of the host name cdsplicwc.cadence.com.co.ltd is 60.190.255.211

Here is the computer which is located in China:

And here is the computer which is located in Holland:

It means that it's not only Chinese local DNS's fault, almost all the DNS has the same issue.

I have also tried to use domain to IP check website, and it also shows that:

It means that almost all DNSs will return cdsplicwc.cadence.com.co.ltd to 60.190.255.211, but it's an incorrect IP, it will cause PSPICE FOR TI shows in information below:

And because we cannot connect to cadence license server, so we can't use PSPICE FOR TI also.

    Hi Floyd,

    Not sure where you get that url. You can check the link by visiting Test Connection.

    Your organization's network setting may prevent a successful connection even if the above URL returns a success. Please generate a log file like this for troubleshooring:

    1. Create a new environment variable "CDS_LIC_QA_TesT". Set it to something like "C:\Cadence\PSpiceTI\LicLog.txt".
    2. Run the installer and wait for the error message, then share the file "C:\Cadence\PSpiceTI\LicLog.tx".
    3. Delete the environment variable "CDS_LIC_QA_TesT".
    4. share the file LicLog.txt

    Step 3 is important because otherwise that file will grow to enormous size over time. We don't want to cause them problems down the road.

    Thanks,
    JC

    Hi Mr Zhu,

    Thanks for your reply.

    I get the url from the original questions:

    Please read original question first, it has discussed a lot about why some machine can't connect to cadence license server.

    I post this thread because I found that the liciense server IP is incorrect is not a fault for a single machine, almost all the DNS server returns incorrect IP of license server, maybe this is the fault of cadence internal network.

    Hi Floyd,

    What you get inside the command window may not be what the program sees as many machines are not directly connected to the internet. For example, I cannot ping the ip inside my company network nor can I do a domain lookup:

    Yet I can run PSpice for TI without issue.

    Note that I can resolve the ip address on my PC at home:
