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(AXI4STREAM_RESET_POSEDGE, bfm_index,
axi4stream_tr_if_0(bfm_index));
wait_on(AXI4STREAM_CLOCK_POSEDGE, 10, bfm_index,
axi4stream_tr_if_0(bfm_index));
Prototype
procedure wait_on
(
phase : in integer;
count: in integer; -optional
bfm_id : in integer;
signal tr_if : inout axi4stream_vhd_if_struct_t
);
Arguments
