SystemVerilog is both a hardware description language and a hardware verification language. It is used to model, design, simulate, verify, test, and implement algorithms or systems for ASICs and FPGAs/SoCs. SystemVerilog is based on the Verilog language with numerous extensions, and in 2009 it ...
1 Verilog always block triggers misbehaving 1 Block of code inside always block is being executed without the input changing in the sensitivity list 0 Which value will be used in an always block? 1 Why always block not reactivating when there is a reassignment of logic ...

But verilog complains about "invalid module item" on the line "datapath d0...", WHY?
Verilog-XL does not mark macro modules(which it expands inline) as cell instances. Refer to the PLI 1.0 Reference and User Guideand theVPI Reference and User Guidefor more information about access routines thatrecognize cells and the use of cells in delay calculation. Note:You do not need ...

I "fixed" this by changing the always block that sets outdata to do so on every clock, meaning the right data gets in there during the setup phase while address is valid on the bus, before the OE strobe comes along. I also refactored my memory bus handling into a submodule (...
So that means two codes I wrote are same in Verilog 2005, right? Another question, you mentioned "for/if/case statement in a module context outside a procedural context is a generate block." Do you mean "if" or "case" out of "always"? I have never see that. Thanks...
aDesign of a micro-UART using Verilog HDL is presented in this paper. The waveform of different signals as shown in simulation results and in oscilloscope guarantee the proper operation of the UART. Due to its compact size, programmability and configurability features, the proposed UART is ideal...
(VHDL, Verilog) Description General Description: What is a "$width" violation, and how do I correct it? Solution In back-annotated (timing) simulation, the timing information is taken into account when simulation is run using the SDF (standard delay format) file. ...
