UVM SEQUENCE ITEM - SEQUENCE - SEQUENCER

Image
 Let's understand what's UVM Seq item, Sequence & Sequencer in a brief way: Sequence item:  It holds the collection of variables (that is, inputs & outputs) Sequence: This is used to create series of sequence items (that is, more scenarios) Sequencer: To arbitrate the sequence to driver For more detailed explanation, you can watch the video I've shared below:

Check for PALINDROME of a String using SV

Image
 CODE: module tb; string s1 = "madam"; string s2; initial begin s2 = {<<8{s1}}; //Storing each character as 8-bits using Streaming Op. if(s1 == s2) $display("\n %s is a Palindrome \n", s1); else $display("\n %s is NOT a Palindrome \n", s1); end endmodule SAMPLE OUTPUT: With Different String match: module tb;   string s1 = "jolly";   string s2;   initial     begin       s2 = {<<8{s1}}; //Storing each character as 8-bits       $display("\nReversal of gn. string is: %s",s2);       if(s1 == s2)          $display("%s is a Palindrome \n", s1);       else          $display("(Given String)%s != %s(Reversed String)",s1,s2);       $display("Therefore, %s is NOT a Palindrome \n", s1);     end endmodule SAMPLE OUTPUT: You can buy me a coffee! https://www.buymeacoffee.com/ch...
