wait_on()

This blocking procedure waits for an event on the ACLK or ARESETn signals to occur before
proceeding. An optional count argument waits for the number of events equal to count.

Example

wait_on(AXI4_RESET_POSEDGE, bfm_index, axi4_tr_if_0(bfm_index));
wait_on(AXI4_CLOCK_POSEDGE, 10, bfm_index,

axi4tr_if_0(bfm_index));

Prototype

procedure wait_on
(

phase : in integer;
count: in integer; --optional
bfm_id : in integer;
path_id : in axi4_path_t; --optional
signal tr_if : inout axi4_vhd_if_struct_t

);
