A HostID is needed by Silvaco to generate a license, please follow the steps below to generate this HostID.

Linux

  • (Install_Directory)libflexlm(Version_Number)(OS_Version)
  • e.g. cd C:sedatoolslibflexlm11.14.2.Rx86_64-windows
• Run the command:
  • .lmutil lmhostid

This command will output a HostID number. Send the HostID to Silvaco for a license to be issued.
