--- Comment #22 from Gökçe Aydos <sourceware.org at aydos dot de> --- I browsed LRM section 21.4 about `$readmemh`, but could not find any info about maximum width (for a memory line that is read by `$readmemh`). I think the range is limited by the maximum width of a vector (`logic`, `bit` etc). Section 6.9.1 states: > Implementations may set a limit on the maximum length of a vector, > but the limit shall be at least 65536 (2^16) bits. I tried to read 1024 bits with Verilator and Vivado. Both tries succeeded. Practically I know that 1024 bit memories exist, e.g., [HBM](https://en.wikipedia.org/wiki/High_Bandwidth_Memory#HBM3). Nevertheless I concur what Olof said: people will typically use 32 to 128 bits and when people will start using objdump, then someone will fix the max 16 byte width. FWIW here are the files I used for testing: a.sv: ``` module a; logic[1023:0] mem [int]; logic clk = 0; initial begin $readmemh("a.memh", mem); foreach (mem[i]) $display("mem[%0d] = %0d", i, mem[i]); $finish; end always #1 clk ^= 1; endmodule ``` a.memh ``` 01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde01234567890abcde ``` -- You are receiving this mail because: You are on the CC list for the bug.
