Re: [vhdl-200x] Clocked Shorthand for Sequencing Testbench Assertions?

Hi Daniel,
That syntax is for assertions right? Are they
using it for testbench sequencing or randomizing
anything too?

The corresponding syntax for VHDL would be PSL in
the VHDL flavor.

You will probably need to read one of the PSL books.

Best,
Jim
