How to describe a process with asynchronous reset in VHDL for the ARRIA 10 FPGA

Hello, i have some trouble with the reset signal. I use VHDL to describe my logic. The target FPGA is an ARRIA 10. I have realized that the reset signal is connected as a global enable signal (ENA)...

    Hi,

    If you put s_data <= data; in the if-else condition, the data will be controlled by arst_n = '0'.

Does s_data even need to be in a clocked process? If s_data can be anything and it's only used when s_valid is valid, could you simply do:

s_data <= data;

or some type of conditional assignment to decide when s_data should be updated?
