3. without inside operator generate random values for the range 34-43
class packet;
rand logic [7:0] a;
constraint range { (a > 34) && (a < 43); }
endclass
module tb;
packet p;

initial begin
p = new();

2. constraint to generate unique numbers between 99 to 100
module tb();
class packet;
rand int a;
real y;
constraint c1{a inside {[990:1000]};}
function void post_randomize();
y=a/10.0;
$display("\t\t\t uniquw valus is %2f", y);
endfunction
endclass
initial begin
packet p1=new();
repeat(20) begin
p1.randomize();
end
end
endmodule

Correct✌

[@SaikiranReddy-c8p]

Could u share u first question in the comments......

[@SaikiranReddy-c8p]

class NumberGenerator;
rand bit [19:0] num;
constraint sum_first_last {
num inside {[100000:999999]};
(num / 100000) + (num % 10) == 8;
}
function void display();
$display("Generated number: %d", num);
endfunction
endclass
module test;
initial begin
NumberGenerator gen = new();
if (gen.randomize()) begin
gen.display();
end else begin
$display("Randomization failed.");
end
end
endmodule

Can we also use int instead of bit data types

[@susheelapatagar]

Yes we can.

[@shivaibara4733]

mam explain how to generate two conscutive ones for 16 bit variable

[@susheelapatagar]

Ok. I will upload one short video for this question.
