I checked the LRM but didn't find anything that was specifically SV about bit masking? bit masking is usually just some and operation with a mask to remove some bits from consideration e.g. parameter mask 8'hF0; assign decode_c = (addr & mask) == 8'hC0; In this example we are looking for the addresses that fall between 0xC0 - 0xCF
I am very new to functions, I have a parameter to specify the input freq(mhz). Would this return a value I could use to specify a vector width? function int _ms_unit_width; int freq_mhz = (int_input_freq_mhz/1000); _ms_unit_width = ($clog2(freq_mhz)+1); endfunction
Early versions of modelsim do not support untyped mailboxes. My recommendation is to always use typed mailboxes anyways - it is safer. class generator; packet pkt; // parameter type T = bit; mailbox #(packet) mbx; function new(mailbox#(packet) mbx); this.mbx = mbx;//(100); endfunction task run(int count); repeat (count) begin pkt = new(); voi
Hi, I have a following statement in my code - genvar sliteIfIter_grp1 generate for ( sliteIfIter_grp1=0; sliteIfIter_grp1 4) localparam MAX_SLITE_GRP1 = 4 else localpara
Hi, I have the following system verilog code to be compiled in VCS. module (....); ..... ...... parameter WIDTH = 8; parameter = {8'h00, 8'hff, 8'h24} ; .... .. endmodule How can i parameterise the size of literals inside the concatenation? so that even if WIDTH changes i need not bother (...)
Hi, I have one SV file where I have to include it in multiple system verilog test cases. Obviously, I will be receiving compilation errors.. Say I have declared a parameter in the include file.. For the first test case, I'll not get any compilation error; when the compiler compiles the second test case and when it compiles the same (...)
Hello, Im new to verilog and am learning it myself.. What im trying to do is to create a simple system, a part of it is an irq timer module... its supposed to generate a pulse determined by a parameter and each pulse should last for 4 clock cycles. here is what i worte (its my first verilog module) module timer( (...)
Here is the code DONT FORGET TO PRES THE HEPLED ME BUTTON module alu(CLK,RESET,A,B,Y,OP,C,N,V,Z); //**************************************************** // 8 bit arithmetic logic unit // // parameter: // CLK.......system clock // RESET.....system Reset // A.........A input // B.........B input // OP........operation to (...)
Hi ASIC_intl, $monitor, once invoked, continuously monitors the values of the variables/signals specified in the parameter list and displays all the parameters in the list whenever the value of ANY one of the variables/signals changes. Since this system task continuously monitors the values, it needs to be invoked only once and hence, (...)
Hi `timescale directive is not used to produce delays like #10 Added after 4 minutes: let us consider `timescale 1ns/1ps reg set; parameter d = 1.55 initial begin #d set = 0; #d set = l; end endmodule The `timescale tells the system to use 1 ns for all reporting and internally use 1 ps
The random generator is a pseudorandom generator. Following excerpt is from the veriloga language manual. For each system function, the seed parameter is an in-out parameter; that is, a value is passed to the function and a different value is returned. The system functions will always return the same (...)
I am studying the verilog-A to do the pll simulation on system level in HspiceRF. This the module of VCO in verilog-A module VCO(in,out); inout in, out; electrical in,out; parameter real Kvco=20.0e6 from (0:1.0e4), Lfkff=0.0 from [0:1.0e4), Lfkfw=0.0 (...)
You cannot do the same thing in verilog as far as I know. However, you can define the state coding using parameter statement. Regards,
