MATLAB: How to set the Vendor for an IP Core generated by HDL Coder

coreHDL Coderipvendor

I am facing the issue that HDL Coder generates Vivado IP cores with different vendor names on different machines. On the windows machine, it is 'mycompany.com' , but on the Ubuntu machine, it is 'user.org'.

Is it possible to set this information, such that the vendor is always the same?

It is currently not possible to specify the IP Core vendor in MATLAB/Simulink, since HDL Coder does not specifically set the vendor flag in the Vivado IP core. Instead, Vivado will derive the default vendor value from either the 'domainname' or 'dnsdomainname' system command.

The development team is aware of this enhancement request, and may consider adding this functionality in a future release.

To work around the issue, you may:

1. Set the correct domain name for your Ubuntu machine.

2. Manually modify line 3 of 'component.xml' inside of the generated IP core folder (for example: ./hdl_prj/ipcore/led_count_ip_v1_0/):

<spirit:vendor>mycompany.com</spirit:vendor>

Hi Stefan,

Yes, the IP core generation feature for Xilinx Vivado will be supported in MATLAB R2014b release. You can already try out this feature in R2014b pre-release.

Thanks, Wang

MATLAB: Does synthesis fail for ZC706 or other high-cost boards when using free Vivado WebPACK edition

This error may be due to a Vivado licensing error. This can be confirmed by opening the Vivado Project File (.XPR) in Vivado IDE, which will reveal the following error on the "Messages" tab:

[Common 17-345] A valid license was not found for feature 'Synthesis' and/or device 'xc7z045'. Please run the Vivado License Manager for assistance in determining which features and devices are licensed for your system.

For example, the no-cost Vivado WebPACK edition only supports a limited set of commercial devices. See the following Xilinx documentation page for a list of all FPGA devices supported by WebPACK:

https://www.xilinx.com/products/design-tools/vivado/vivado-webpack.html#architecture

While Vivado WebPACK supports the low-cost XC7Z020 device used on Zedboard and Xilinx ZC702, an additional license is required for the synthesis of the XC7Z045 Zynq device used on Xilinx ZC706.
