To represent the functionality of the VHDL code, the import function chose various mathematical and logical operation blocks and used a Multiport Switch block for the case statement logic. Get open_system('ope
Data Types:double|single|int8|int16|int32|int64|uint8|uint16|uint32|uint64 Vector of dimensions, specified as a vector of positive integers. Each element represents a dimension of the input array. The lengths of the output in the specified operating dimensions are 1, while the others remain...
It may come as a surprise that "initial" can be used in Verilog code for synthesis, but as it turns out, this usage is widely supported. So this keyword is definitely the preferred method if the synthesizer supports it (in other words, this usage of "initial" is explicitly mentioned in...
VeriStatement *new_node = veri_file::AnalyzeStatement("A2:cover property (test2 == 1'b1) ;", veri_file::SYSTEM_VERILOG, dummy_lf /*could be 0, may use node.Linefile()*/, scope) ; if (new_node) { // Something went wrong st = node.AddStatement(new_...
A signal is updated whenever the process that is assigned in suspends (eg hits a wait statement or finishes when it has been triggered by a signal in the senstivity list). A variable is updated immediatly. If you dont know the difference, then you should always stick wi...
So the system only updates when, as far as I can tell, max_reset is 1. I've tried to change the code by changing max_reset to a reg and putting it into an always statement that checks hard_reset and timer_reset via if statements and assigns max_reset a value directly, but...
Some Verilog designs use a `define statement, possibly located inside a file referenced by an `include statement, to control something managed with `ifdef or `ifndef. Instead of using a `define statement, you can define the Verilog macro with a Quartus setting in the .q...

The assert statement from SystemVerilog is supported in its most basic form. In module context: assert property (<expression>); and within an always block: assert(<expression>);. It is transformed to an $assert cell. The assume, restrict, and cover statements from SystemVerilog are also supp...
If I understand pancho_hideboo's code, he is generating an autonomous clock with a given phase but he is not muxing one of the input phases out. In my opinion, you need to check for changes of either P or IN and then select the correct output using a case statement. Apr 29, 2011...
