Unpacked unions are not synthesizable. They are an abstract type which are useful for high-level system and transaction level models. As such, it may be useful to store any type in the union including 4-state t
SystemVerilog always_comb, always_ff. New and Improved. Verilog reg, Verilog wire, SystemVerilog logic. What's the difference? Verilog twins: case, casez, casex. Which Should I Use? SystemVerilog Arrays, Flexible and Synthesizable SystemVerilog Struct and Union - for Designers too...
So it only does the first loop. I guess this is a known bit of missing functionality? I guess there might be issues in how the constant number of loops is lowered to SV? I think it needs to end up obviously still constant so it is synthesizable....
- New operator and enhanced loop control have been added for improved design & verification. New always_type blocks show design intent and help ensure construction of proper hardware designs. Enhancements were added to tasks and functions to increase their capabilities. Unique and priority are new ...
// Use the "dword view" of the union in a generate loop generate genvar gi; for (gi=0; gi<2; gi=gi+1) begin : gen_mem // instantiate a 32-bit memory mem_32 u_mem ( .D (my_opcode_in.dword[gi]), .Q (my_opcode_out.dword[gi]), ...
for testbench modeling, whereas the static nature of other variable types make them appropriate for modeling hardware, which is also static in nature. Because of the dynamic nature of classes, they are not considered synthesizable constructs. Classes are intended for verification routines and highly ...
