There are cases where tRISE (rise time) and tFALL (fall time) for each I/O Standard are not listed in the handbook. Is there a way to find out?
You can check tRISE and tFALL in the Quartus II compilation report.
If you already have a design, try compiling it.
The confirmation method for Quartus II Ver.9.1 is shown below.
