是APB slave的接口信号 // Interface input [31:0] status32, input [15:0] status16, input [ 7:0] status8, output reg [31:0] control32, output reg [15:0] control16, output reg [ 7:0] control8 是一个自定义模块的寄存器,其中status32是read_only wire apb_write = psel & penable &...
下面是一个非状态机写法的APB slave 的verilog实例,大家可以在此基础上设计自己APB slave接口的自定义模块,将外设挂接到SoC上。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // Sample APB register code// Standard read/write registers// Adress offset:// 0x00 : 32 bit read of status32 register...
根据上面的状态转换图可以很轻松地编写基于FSM的VerilogHDL。下面是一个非状态机写法的APB slave 的...
HDL Used : Verilog Simulator Tool Used: ModelSIM Synthesis Tool Used: Quartus Prime Family: Cyclone V Device: 5CSXFC6D6F31I7ES Design Modules AHB Slave Interface An AHB bus slave responds to transfers initiated by bus masters within the system. The slave uses a HSELx select signal from the...
AMBA-Xactor is proven VIP enabling SoC and IP developers to perform comprehensive functional verification of their IP and SOCs incorporating full range of AMBA bus protocols (AXI4 - Full, Lite, Stream, AXI3, AHB, APB) master, slave, and interconnects functionalities and ensure compliance to the...
A full AHB or AHB-Lite master, such a microprocessor, can connect to its AHB slave interface, and an APB4, APB3, or APB2 peripheral can connect to its APB master port. Furthermore, the endianness and the data bus widths of the AHB and APB interfaces are independently configurable. The...
Verilog prajwalgekkouga/AHB-to-APB-Bridge Star58 Code Issues Pull requests The AHB to APB bridge is an AHB slave and the only APB master which provides an interface between the highspeed AHB and the low-power APB. Read and write transfers on the AHB are converted into equivalent transfers ...
Here main aim is to reduce human interface in design part so we can reduce common syntax errors. Per generates the Verilog design code of APB slave and its corresponding test bench, where all its specifications are there in XML script. This code is simulated in QuestaSim. Finally wave forms...
The I2C-to-APB Bridge Reference Design provides an interface between the low speed I2C Bus and the AMBA 3 APB Bus. The design is implemented in Verilog HDL and comes in .ipk format that is installed within Lattice Propel™ Builder software as an IP. Implementation is done with...
