简易cpu的设计

c54x的VeriLog程序代码 也是opencoreip-C54x is the Verilog code opencoreip

主要是基于FPGA(EP2C8Q208I8)下的SRAM驱动，SRAM型号为IS61LV25616，程序语言为Verilog,开发环境为quartusII 7.0,为一工程，可直接下载到FPGA中，含电路图(Mainly based on FPGA (EP2C8Q208I8) driving under the SRAM, SRAM model IS61LV25616, programming language for Verilog, a development environment for quartusII 7.0, for a project, can be downloaded directly to the FPGA, including circuit diagrams)

VHDL operators basics

ppm调制的verilog代码 可实现ppm调制(ppm modulation verilog code ppm modulation)

最完整最实用的8051的软核，用VHDL语言编写全部原代码，并有详细的注释介绍，对开发增强型多功能单片机或RSIC单片机内核和单片机SOC应用非常有参考价值-most complete most practical of the 8051 soft-core, with all the preparation VHDL source code, and the Notes for a detailed briefing on the development of an enhanced multi-purpose microcontroller core or RSIC microcontroller and microprocessor applications SOC very valuable reference

This is the Spartan 3E tutorial_02.

序列检测VHDL源代码，ATERA平台编译。详细的报表说明和模拟源代码。

Testbench 不仅要产生激励也就是输入，还要验证响应也就是输出。当然也可以只产生 激励，然后通过波形窗口通过人工的方法去验证波形，这种方法只能适用于小规模的设计(The Testbench not only to generate incentives to input, verify that the response is output. Of course, can only produce Incentive, and then the waveform by the waveform window by artificial means to verify, this method is only applicable to small-scale design)

very good code for edge detection based on vhdl programming.
