I write an easy VHDL code (fig1) in order to activate Output as PULLUP. In xdc file (fig2) I use PULLTYPE constraint to activate output as PullUp. In the floorplan (fig3) we can see PAD block which has PullUp constraint in its properties. But, is th...
This is a simple CPU architecture that I used to verify that I understand how to use FPGAs, VHDL, and write a CPU using Vivado on Arty S7. This is my largest project to date. - cas-mls/cpu2
I am working with a large reference design for a big Virtex 7 FPGA in Vivado, supplied by the hardware vendor. The reference design has sections that I want to delete from the design in order to clear up space for the functions I am adding. I have modified the VHDL files to not refer...
Hi guys I want to read data from a sdram memory. I'm using vivado and kintex7. I changed the xdc file according my board. but I received this errors...
A fantastic free resource that all FPGA front end developers need to be aware of is “fizzim”. It is a tool that automatically writes VHDL/Verilog code for your state machine provided that you draw the state machine for the tool.

后者,提高设计的抽象程度的例子是高层次综合(High-Level Synthesis,HLS),是指把高层次语言例如C++、Python、Matlab,通过编译器,解析、优化、转化为低层次语言例如Verilog/VHDL。因为大多数应用,在算法层面,已经有许多软件工程师提供了完善且优秀的代码,例如OpenCV、PyTorch等等,如果能把这些已经描述好的功能直接又快又好...
I understand your issues with VHDL. 80% if what I do is VHDL and, because you can write very terse and obscure Verilog my headaches generally come from Verilog code written by people who like to impress themselves with their Verilog knowledge. If you spend any significant length of tim...
From HDL to Bitstream: Unraveling the FPGA Design Journey In the realm of FPGA design, the journey begins with code in aHardware Description Language(HDL), such as Verilog or VHDL. This code serves as the blueprint for the intended functionality to be implemented on the Field-Programmable Gate...
In most FPGA architectures the block RAM primitives are fully synchronous components. This means that if we want the synthesis tool to infer block RAM from our VHDL code, we need to put the read and write ports inside of a clocked process. Also, there can be no reset values associated wit...
