Verilog math operations and comparison operations (such as the less-than and greater-than operators) use the data type of the operands to determine whether to perform signed or unsigned operations. The general rule is that if all operands in the expression are signed, then a signed operation ...
There you have three registers (g0,g1,g2 and each needs an load enable. Thus you need an ld0, ld1, ld2. Verilog is not like C where you can just re-use a variable multiple times. Just remember that it is a massive parallel language: all of the assigns everywhere in any file ar...

Arrays of net and real data typesIn the Verilog-1995 standard, only one-dimensional arrays of reg, integer and time variables can be declared. Arrays of the real and realtime variables are not allowed. Arrays of any of the net data types, such as wire, are also not permitted....
Unfortunately I inherited the design with the construct above and it's a pure Verilog implementation, not SystemVerilog. I was trying to overhaul the existing testbench using Verilator. Just out of curiousity, I saved the adder example above to design.sv and tried to compile it using VCS on...
The problem is due to the difference between aregdeclaration and awiredeclaration in Verilog. When you have a declaration of type reg that looks like : reg my_signal = initial_value; This is treated as an initial condition. However if you have a statement that looks like : ...
