本文采用浅显易懂的描述方式,结合具体的c代码例子,详细描述了常用三种指针的设计类型,以及其作为顶层函数参数时,采用不同的编码风格和HLS约束策略,满足设计者对指针作为RTL接口的需求。 1.基本指针类型 基本指针类型指的是指针没有运算或者没有多次的存取(读写)。指针作为top函数的参数时,指针综合为wire型或者握手协议...
The name of this function must be specified in the block parameter dialog box under the Block Configuration parameter. The configuration M-function does the following: • It specifies the top-level entity name of the HDL component that should be associated with the black box. • It selects...
The results I have shown in my first post have been generated by using Vivado HLS only. I used the PCORE for EDK export and selected evaluate VHDL to generate the code. So all the ports are top level ports and should not be optimized away. When running syn \+ P&R with the vhdl file...
X-Ref Target - Figure 3-14 Figure 3-14: Create and Package New IP Wizard: Package a Specified Directory 2. Make your selections from the following options: ° Directory: The location of the IP. IMPORTANT: If you are using Vivado High Level Synthesis (HLS), you need to specify the ...

• If you want to synthesize functions that are not in the hierarchy under the top-level function for synthesis, you must merge the functions into a single top-level function for synthesis. Test Bench When using the Vivado® HLS design flow, it is time consuming to synthesize a ...
Note: If %log_dir% is not specified, a file named install_drivers_wrapper.log will be placed under %VIVADO_INSTALL_DIR%. 2. To install the Linux driver, do the following: a. Enter the following commands as root: ${vivado_install_dir}/data/xicom/cable_drivers/lin64/install_script/ ...
A platform project begins with a Vivado Design Suite project file (<platform>.xpr) as the starting point to build the Xilinx Support Archive (XSA) file for hardware components. After the project is created, a block design must be created. The block desig
