ok prashant
bellow code are code of env and program(testcase)
`include"intf_spi.sv"
`include"scb_spi.sv"
class environment;
virtual intf_spi.dut intf1;

mon_spi mnt;
dr_spi drv;
scoreboard scb;
mailbox gen_dr;
mailbox gen_scb;
mailbox mon_scb;
//virtual intf_spi.test intf2;
function new(input mailbox gen_dr,virtual intf_spi.dut intf1,virtual intf_spi.test intf2);
this.intf1=intf1;
this.intf2=intf2;
this.gen_dr=gen_dr;
endfunction
task build();
