Regarding assertion property

In reply to Maitri@07:

I believe you want

property check_out_val(outval,writes,command);
   int  temp_data1,temp_data2;
   @(posedge amd_apb_if.PCLK) disable iff(amd_apb_if.rst)
	    command |->  (1,temp_data1 = writes) ##1  (1,temp_data2 = writes) ##3 (outval == (temp_data1 + temp_data2)) ;
 
   endproperty
