PHASE 7 RECEIVER
In this phase, we will write a receiver and use the receiver in environment class to collect the packets coming from the switch output_interface.
Receiver collects the data bytes from the interface signal. And then unpacks the bytes in to packet and pushes it into channel for score boarding.
Receiver class is written in Reveicer.sv file.
1) Extend vmm_xactor and define Receiver class.
class Receiver extends vmm_xactor;
1) Declare a virtual output_interface. We will connect this to the Physical interface of the top module, same as what we did in environment class.
virtual output_interface.OP output_intf;
2) Declare a channel "rcvr2sb_chan" which is used to send the packets to the score board
Packet_channel rcvr2sb_chan;
3) Define new constructor with arguments, virtual input interface and a channel which is used to send packets from the receiver to scoreboard. Implement the restof the logic as it was done in the driver constructor.
function new(string inst = "class",
int unsigned stream_id = -1,
virtual output_interface.OP output_intf_new,
Packet_channel rcvr2sb_chan);
super.new("Receiver",inst,stream_id);
this.output_intf = output_intf_new ;
if(rcvr2sb_chan == null)
`vmm_fatal(log,"rcvr2sb_channel is null");
else
this.rcvr2sb_chan = rcvr2sb_chan;
`vmm_note(log,"Receiver created ");
endfunction : new
4) Define the main() method.
In start method, do the following
First call the super.main() method.
Then start a thread which collects the data from the outputinterface and then unpack the data to a packet and put into channel.
forever
begin
repeat(2) @(posedge output_intf.clock);
wait(output_intf.cb.ready)
output_intf.cb.read <= 1;
repeat(2) @(posedge output_intf.clock);
while (output_intf.cb.ready)
begin
bytes = new[bytes.size + 1](bytes);
bytes[bytes.size - 1] = output_intf.cb.data_out;
@(posedge output_intf.clock);
end
bytes[bytes.size - 1] = output_intf.cb.data_out;
output_intf.cb.read <= 0;
@(posedge output_intf.clock);
`vmm_note(this.log,"Received a packet ");
pkt = new();
pkt.byte_unpack(bytes);
pkt.display("rcvr");
rcvr2sb_chan.put(pkt);
bytes.delete();
end
Receiver Class Source Code:
`ifndef GUARD_RECEIVER
`define GUARD_RECEIVER
class Receiver extends vmm_xactor;
virtual output_interface.OP output_intf;
Packet_channel rcvr2sb_chan;
function new(string inst = "class",
int unsigned stream_id = -1,
virtual output_interface.OP output_intf_new,
Packet_channel rcvr2sb_chan);
super.new("Receiver",inst,stream_id);
this.output_intf = output_intf_new ;
if(rcvr2sb_chan == null)
`vmm_fatal(log,"rcvr2sb_channel is null");
else
this.rcvr2sb_chan = rcvr2sb_chan;
`vmm_note(log,"Receiver created ");
endfunction : new
task main();
logic [7:0] bytes[];
Packet pkt;
super.main();
`vmm_note(this.log," started main task ");
forever
begin
repeat(2) @(posedge output_intf.clock);
wait(output_intf.cb.ready)
output_intf.cb.read <= 1;
repeat(2) @(posedge output_intf.clock);
while (output_intf.cb.ready)
begin
bytes = new[bytes.size + 1](bytes);
bytes[bytes.size - 1] = output_intf.cb.data_out;
@(posedge output_intf.clock);
end
bytes[bytes.size - 1] = output_intf.cb.data_out;
output_intf.cb.read <= 0;
@(posedge output_intf.clock);
`vmm_note(this.log,"Received a packet ");
pkt = new();
pkt.byte_unpack(bytes);
pkt.display("rcvr");
rcvr2sb_chan.put(pkt);
bytes.delete();
end
endtask : main
endclass
`endif
Now we will take the instance of the receiver in the environment class.
1) Declare a channel "rcvr2sb_chan" which will be used to connect the scoreboard and receiver.
Packet_channel rcvr2sb_chan;
2) Declare 4 receiver object "rcvr".
Receiver rcvr[4];
3) In build method, construct the rcvr2sb_chan.
rcvr2sb_chan = new("rcvr2sb","chan");
4) In build method, construct the receiver object. Pass the output_intf and rcvr2sb_chan. There are 4 output interfaces and receiver objects. We will connect one receiver for one output interface.
foreach(rcvr[i])
rcvr[i] = new($psprintf("Rcvr-%0d",i),i,output_intf[i],rcvr2sb_chan);
5) To start the receiver activities, call the start_xactor() method of rcvr objects in the start() method of Environment class.
rcvr[0].start_xactor();
rcvr[1].start_xactor();
rcvr[2].start_xactor();
rcvr[3].start_xactor();
6) Call the stop_xactor() method of the receiver object in the stop() method of the Environment .
rcvr[0].stop_xactor();
rcvr[1].stop_xactor();
rcvr[2].stop_xactor();
rcvr[3].stop_xactor();
