UVM Questasim simulation
HI , I am trying to simulate a generic ALU in Systemverilog UVM test environment . My add_i is random input signal , but when i open my wave i dont see it toggling , but the display function reports it is being toggled ? here are my files : // alu package file // package alu_pkg; //----Transaction Class---- class transaction; //declaring the transaction items rand bit [3:0] a; rand bit [3:0] b; bit [6:0] c; rand bit add_i; function void display(string name); $display("-------------------------"); $display("- %s ",name); $display("-------------------------"); $display("- a = %0d, b = %0d",a,b); $display("- c = %0d",c); $display("-------------------------"); $display("-- ADD = %b --",add_i); endfunction endclass //---------------------------------------// //-----------Driver Class------------------ class driver; //used to count the number of transactions int no_transactions; //creating virtual interface handle virtual intf_alu#(.WORD_LENGTH(4)) vif; //creating mailbox handle mailbox gen2driv; //constructor function new(virtual intf_alu vif,mailbox gen2driv); //getting the interface this.vif = vif; //getting the mailbox handles from environment this.gen2driv = gen2driv; endfunction //Reset task, Reset the Interface signals to default/initial values task reset; wait(vif.reset); $display("[ DRIVER ] ----- Reset Started -----"); vif.a <= 0; vif.b <= 0; vif.valid <= 0; vif.add_i <= 0; vif.mul_i <= 0; vif.sub_i <= 0; vif.div_i <= 0; vif.and_i <= 0; vif.or_i <= 0; vif.xor_i <= 0; wait(!vif.reset); $display("[ DRIVER ] ----- Reset Ended -----"); endtask //drivers the transaction items to interface signals task main; forever begin transaction trans; gen2driv.get(trans); @(posedge vif.clk); vif.valid <= 1; //vif.add_i <= 1; vif.a <= trans.a; vif.b <= trans.b; @(posedge vif.clk); vif.valid <= 0; //vif.add_i <= 0; trans.c = vif.c; @(posedge vif.clk); trans.display("[ Driver ]"); no_transactions++; end endtask endclass //---------------------------------------// //----Generator Class------------------ class generator; //declaring transaction class rand transaction trans; //repeat count, to specify number of items to generate int repeat_count; //mailbox, to generate and send the packet to driver mailbox gen2driv; //event, to indicate the end of transaction generation event ended; //constructor function new(mailbox gen2driv); //getting the mailbox handle from env, in order to share the transaction packet between the generator and driver, the same mailbox is shared between both. this.gen2driv = gen2driv; endfunction //main task, generates(create and randomizes) the repeat_count number of transaction packets and puts into mailbox task main(); repeat(repeat_count) begin trans = new(); if( !trans.randomize() ) $fatal("Gen:: trans randomization failed"); trans.display("[ Generator ]"); gen2driv.put(trans); end -> ended; //triggering indicatesthe end of generation endtask endclass //---------------------------------------// //----Environment Class------------------ class environment; //generator and driver instance generator gen; driver driv; //mailbox handle's mailbox gen2driv; //virtual interface virtual intf_alu#(.WORD_LENGTH(4)) vif; //constructor function new(virtual intf_alu vif); //get the interface from test this.vif = vif; //creating the mailbox (Same handle will be shared across generator and driver) gen2driv = new(); //creating generator and driver gen = new(gen2driv); driv = new(vif,gen2driv); endfunction // task pre_test(); driv.reset(); endtask task test(); fork gen.main(); driv.main(); join_any endtask task post_test(); wait(gen.ended.triggered); wait(gen.repeat_count == driv.no_transactions); endtask //run task task run; pre_test(); test(); post_test(); $finish; endtask endclass //---------------------------------------// endpackageAshling RiscV NiosV errors
Hi I am trying to compile a simple hello world on NiosV targeting a CycloneIVE FPGA on DE2-115 board p/n : EP4CE115F29C7. But when i build project in Ashling RiscFree i get these errors which i dont have any idea what these referring to : Below i am pasting the complete system.h file : /* * system.h - SOPC Builder system and BSP software package information * * Machine generated for CPU 'Nios_gen_purpose' in SOPC Builder design 'SOC_uart' * SOPC Builder design path: ../../SOC_uart.sopcinfo * * Generated: Tue May 27 13:03:27 PKT 2025 */ /* * DO NOT MODIFY THIS FILE * * Changing this file will have subtle consequences * which will almost certainly lead to a nonfunctioning * system.
