The first two statements in the declarative region of the VHDL file declare the RAM type and its signal. The RAM is dynamically sized from the generic inputs. 1 2 3 4 -- The FIFO is full when the RAM contains ra
Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. In previous tutorials in this series we have been writing all our code in the main VHDL file, but normally we wouldn’t do that. We create ...
Instead of using VHDL or Verilog to configure these logic primitives, CLB is programmed with a GUI-based SysConfig tool and function calls. Since the configuration method is different, the CLB is technically not a CPLD or FPGA, but it can be used to achieve identical results. The CLB holds...

To read a value from the UART: iUart can be checked to see if data is present in the FIFO, if it is assert RXRE in the oUart register, on the next clock cycle the data will be present in the iUart register. The baud rate of the UART can be changed by rebuilding the VHDL proj...

To verify that the SmartModels have been set up correctly, enter the following in the ModelSim command window: VSIM>vsim unisim.ppc405 If there are no errors upon loading, the simulator is set up correctly. NOTE: If you are running ModelSim Standalone with a ".mpf" file, make sure tha...
You need to clean up your VHDL before you work on the timing constraints. Besides a couple of syntax errors for missing "then"s, you have some problems with your process statements. The sensitivity lists for registered logic should contain only the clock and asynchronous control signals...
The ASYNC_REG property is supposed to solve this by ensuring that the FFs stay "near" eachother - in the same slice if possible. If they are really in the same slice, then I can't see any way for the route between them to be anything but really short. If they are in neighboring ...
In recent years, the line between hardware and software has blurred. Hardware now engineers create the bulk of their new digital circuitry in programming languages such as VHDL and Verilog. This article will help you make sense of programmable logic.A qu
