Using Gen 8.6 CSE Construction Client, when an action block is generated, the generation is not complete and the following error message is output to iefmd.log. TLclst::build - Must have a destination operand
Gen Client Server Encyclopedia
The "Must have a destination operand
" message means that there may be a corruption in an action block statement line.
It is suggested to check if Toolset generation has same problem or not.
Also run a CSE Encyclopedia Validate Report and check for errors.
To requested assistance with model corruption errors please create a Gen support case at Broadcom Support.
