pico-png is a VHDL implementation of a PNG encoder, as specified in ISO/IEC 15948:2003. It includes a deflate compression according to RFC1950 and RFC1951.

Creating symbol for demo_device.vhdl "demo_device" -> demo_device-demo_device.svg. Produces the following: Symbolator can render to PNG bitmap images or SVG, PDF, PS, and EPS vector images. SVG is the default. Symbolator requires either Python 2.7 or Python 3.x, Pycairo, and Pango. The installation script depends on setuptools.

VHDL（VHSIC Hardware Description Language）是一种硬件描述语言，被用于描述数字和混合信号系统，如FPGA（现场可编程门阵列）和ASIC（专用集成电路）。 本资源对pico-png的详细介绍包括了其产品特点、架构概述以及与同类型商用IP核IPB-PNG-E的性能比较。

It parses the entity declaration of your VHDL source code and produces various types output. It is written in C++ and runs on Linux and Windows plattforms. Currently the following transformations are implemeted: VHDL to schematic symbol as FODG, SVG, and PNG files, VHDL to port overview/list as markup, markdown, and LaTeX tables.

vhdl是fpga开发中不可或缺的一部分，它具有强大的硬件描述能力、出色的仿真能力和广泛的工业应用。vhdl作为fpga开发的主流语言，仍然是许多企业的首选，特别是在高可靠性和高复杂度的应用领域，如航空航天、工业自动化和通信系统。

从平均值也能看出Verilog热度高于VHDL！ 如果从全球区域使用情况来看： 可见，在中国、美国、俄罗斯以及加拿大使用Verilog的更多，而欧洲国家以及巴西、澳大利亚使用VHDL更多！ 中国的情况更加突出，Verilog对于VHDL的热度更明显： 美国情况类似：

2017年3月3日 · I want to export the Modelsim waveforms of my simulated design in a form where they can look decent when printed. To be more specific, without the black background, in a vector format preferably. Not something like this: But instead like this: The schematics are indicative, but I hope you get the point. Is there any way to achieve that?

This VHDL tutorial is to tell you how to read images in VHDL in a way that the images can be loaded into the block memory of the FPGA during synthesis or simulation. Since VHDL cannot read image files such as BMP, JPG, TIF, etc. directly, images are required to be converted into binary text files so that VHDL can read them using the TEXTIO VHDL ...

2022年7月2日 · VHDL (VHSIC Hardware Description Language) is a hardware description language used in digital circuit design and simulation. A VHDL process is a block of sequential statements that execute concurrently in a specific order. It is the basic building block for designing digital systems using VHDL.

2014年9月10日 · VHDL和Verilog都是目前使用最多的两种硬件语言（HDL），前者最开始是美国军方的标准，后来慢慢普及，最早的硬件工程师使用的基本都是VHDL，这也是为什么现在很多高校开设的也都是VHDL课而不是Verilog课程，因为那些老师最开始接触的都是VHDL，所以他们教授 …
