Avoiding Assign Statements in Verilog NetlistsThe assign statement in Verilog allows two nets or ports to be connected to each other. In a netlist this occurs in one of two cases:An input port entering a module is directly connected to an output port without any logic in between:assign Monit...
用错assign的一个例子 试用Verilog中的=, <=和assign - 博客园Synchronous sequential circuits do not process their Verilog statements in sequence within the always block.我理解这句话的前提是用了<=而不是=。 在这个帖子里,我用了条assign,这是错的。程序能跑对是运气好,assign op = inst[7:6];后就...

elements.F eedthrough Nets HDL Compiler creates assign statements in the design when two ports are connected without logic between them. If a feedthrough has an output port connected to an input port without any logic in between, i t causes Design Compiler to add the assign statement in the ...
assign clk50m_buffered = clk50m_buffered_BUFG; Using design compiler I would use set_fix_multiple_port_nets -feedthroughs -outputs [get_designs *] before writing out the netlist to avoid assign statements. How do I avoid assign statements in a netlist in Vivado? Thanks, Gregフ...
