Name

Description

 

 

<project_dir>/<component_name>/simulation/functional

 

 

simulate_mti.do

ModelSim macro file that compiles the

 

functional netlist, loopback HDL, and

 

demo HDL source. The script also loads

 

and runs the simulation for 8 μs.

 

 

wave_mti.do

ModelSim macro file that opens a wave

 

window and adds key signals to the wave

 

viewer. The wave_mti.do file is called by

 

the simulate_mti.do macro file.

 

 

simulate_ncsim.sh

Shell scripts that compile the functional

simulate_ncsim.bat

netlist and loopback HDL source. The

 

script also launches NCSIM and runs the

 

simulation for 8 μs.

 

 

wave_ncsim.sv

NCSIM macro file that opens a wave

 

window and adds key signals to the wave

 

viewer. The wave_ncsim.sv file is called by

 

the simulate_ncsim.sh or

 

simulate_ncsim.bat file.

 

 

simulate_vcs.sh (verilog only)

Shell script that compiles the functional

 

netlist and example design. The script also

 

runs the functional simulation using VCS.

 

 

vcs_session.tcl (verilog only)

VCS tcl script that opens a wave window.

 

This macro is called by the simulate_vcs.sh

 

script.

 

 

vcs_commands.key (verilog only)

VCS command file. This file is called by the

 

simulate_vcs.sh script.

UG154 specifications

Xilinx UG154 is a comprehensive user guide that provides in-depth information about the architecture, features, and technologies of Xilinx's FPGA (Field Programmable Gate Array) devices. This guide is particularly vital for developers, engineers, and designers who work with Xilinx products, as it serves as a key resource throughout the development lifecycle.

One of the main features of Xilinx UG154 is its coverage of the device architecture, which details the programmable logic cells, configurable interconnects, and I/O capabilities. Xilinx FPGAs are known for their flexibility and scalability, allowing designers to implement complex digital circuits and systems that can be modified post-manufacturing, enabling rapid prototyping and iterative design processes.

Another key aspect highlighted in UG154 is the technological advancements in the latest Xilinx architectures, such as UltraScale and UltraScale+. These architectures incorporate advanced process technologies, providing improved performance and power efficiency. High-speed serial transceivers, embedded processing capabilities, and extensive memory options are also discussed, showcasing how these features enhance system integration and reduce design time.

The guide also delves into Xilinx's software ecosystem, featuring the Vivado Design Suite, which streamlines the design process through integrated design tools and a unified development environment. The Vivado suite supports various high-level synthesis, simulation, and analysis tools, facilitating a smoother transition from concept to implementation.

In addition to hardware and software integration, UG154 covers the importance of IP cores, which are pre-designed functional blocks that can be easily integrated into FPGA designs. Xilinx provides a vast library of IP cores, ranging from basic logic functions to sophisticated signal processing algorithms, enabling engineers to accelerate development without sacrificing performance.

Another focus of UG154 is the emphasis on design best practices and optimization techniques that can be employed to maximize the capabilities of Xilinx devices. Topics such as timing closure, resource optimization, and power management are among the critical areas addressed, which help designers achieve the desired performance within the constraints of their applications.

Overall, Xilinx UG154 serves as a vital resource that equips engineers with the knowledge and tools necessary to leverage the full potential of Xilinx FPGAs. By understanding the features, technologies, and architectural characteristics detailed within this guide, designers can create innovative solutions across a range of applications, including telecommunications, automotive, aerospace, and industrial automation.
