If this latch is implemented in an FPGA that has 4-input lookup tables (LUTs), then only one lookup table is needed, as shown in Figure 3a. A style of VHDL code that uses logic expressions to describe this circuit is given in Figure 2. Figure 1 depicts a gated RS latch circuit. But first we will show how storage elements can be created in an FPGA without using its dedicated flip-flops.

ALTERA QUARTUS II ADDER LAB HOW TO

We will show how to make use of these flip-flops in Part IV of this exercise. Part I Altera FPGAs include flip-flops that are available for implementing a user’s circuit. The design unit was not found.Laboratory Exercise 3 Latches, Flip-flops, and Registers The purpose of this exercise is to investigate latches, flip-flops, and registers. # ** Error: (vsim-3033) PPA.vo(5086): Instantiation of ‘cycloneii_io’ failed.

We’ll click the Simulate -> Start Simulation. We need to start the simulation and tell it where to find the Cyclone IVe I/O pin library. # ** Error: (vsim-3033) SimpleInverter_6_1200mv_85c_slow.vo(77): Instantiation of 'cycloneive_io_ibuf' failed. # C:\altera\11.0sp1\simulation\modelsim\gate_work # ** Error: (vsim-3033) SimpleInverter_6_1200mv_85c_slow.vo(67): Instantiation of 'cycloneive_io_obuf' failed. If you try to begin the gate-level simulation like we did with the RTL simulation (double clicking the work/SimpleInverter module), you’ll be given the following error: Now comes a little trick to start this simulation. If you get a NativeLink error, something like “ error deleting "msim_transcript": permission denied.” you’ll need to make sure you close your current ModelSim environment, or at least stop the current simulation. Also, select the ModelSim-Altera as the simulation tool and select the format as Verilog HDL. When using the New Project Wizard, make sure to select the DE0-Nano’s FPGA which is the EP4CE22F17C6. Start by creating a new project in Quartus II.

ALTERA QUARTUS II ADDER LAB INSTALL

Note that you will have to install the ModelSim (Altera Version) software separately from Quartus, Altera’s website makes it seem like they come bundled but this is not the case. I recommend installing both tools at the same time, from the same release.

You can see the versions of my software aren’t the same, this is probably why I have the EDA tool pathing issue described below. ModelSim 10.0C (Quartus 11.1) Starter Edition.

ALTERA QUARTUS II ADDER LAB MANUAL

Going through the examples in the DE0-Nano User manual should be sufficient.įor the tutorial, I’m using the following versions of the software: This tutorial assumes you have some basic experience working with Quartus II. This is a tutorial to walk you through how to use Quartus II and ModelSim software together to create and analyze a simple design (an inverter), then we’ll compare the RTL and Gate-Level simulations with the results on a DE0-Nano.
