Active-HDL Does not Start after System Clock Time Change


Windows keeps a record of the last date when a file was created on the system. If the system clock was moved forward and a file was created, that will be the latest file creation date. When the system clock is set back again, the last file creation date will be ahead of the system clock, making it look like the system clock has been set back. All files with creation dates behind the system clock date must be removed from the system before the license will work. First ensure that the machines date and time are set correctly. Then follow instructions below.

  1. Install Cygwin

  2. Run the following commands:

touch c:/aldec.tmp
find c: -newer c:/aldec.tmp -exec touch {} \;  
rm c:/aldec.tmp
