Slow Response While Updating The Test Table In A Semiconductor Multi Test Step

Users may encounter a slow response while scrolling the test table in a Semiconductor Multi Test step when their test program meets the following criteria:
  • The Pin Map file uses a relative file path
  • Both of the following settings are enabled for the 'Current sequence file directory':
    • The Search Directories setting
    • The 'Search Subdirectories' option
You can check these settings using the TestStand Sequence Editor menus by selecting 'Configure' >> 'Search Directories...'

Workaround:

Users can work around this issue using one of the two methods described below.

Method 1:
Relocate the pin map file to be placed within the same directory as the test program sequence file.

Method 2:
Perform the following steps:
  • From the TestStand Sequence Editor menus, select 'Configure' >> 'Search Directories...'
  • Disable the 'Search Subdirectories' option for 'Current sequence file directory'
  • Click 'OK' to save the settings and close the dialog
  • From the TestStand Sequence Editor menus, select 'Semiconductor Module' >> 'Edit Test Program: <Sequence File Name>...' to open the Test Program Editor
  • Using the Test Program Editor, update the Pin Map File Path and ensure that the updated relative path correctly resolves without errors
