Unable to find the software for XILINXLOGICORE

Hello,

I want to set the Floating Point IP Library to the XILINX IP Logicore, but I get the following error from the Configuration Parameters of Simulink: "Unable to find the software for XILINXLOGICORE. Make Sure it is installed with Xilinx ISE and use hdlsetuptoolpath to set up Xilinx ISE."

My configuration:

• Windows 10 64-bits
• Matlab 2019b
• Xilinx Vivado 2019.2 with System Generator 2019.2

I already setup the path with the following command:

hdlsetuptoolpath('ToolName', 'Xilinx Vivado', 'ToolPath', 'D:\Xilinx\Vivado\2019.2\bin');

The command !vivado executes Vivado 2019.2.

Could you please tell me how to set the Floating Point IP Library to the XILINX IP Logicore ?

It is possible Xilinx LOGICORE is not avaialble with Vivado and you need to setup Xilinx ISE to use it. Please check Xilinx Documentation.

Per HDL Coder documentation Xilinx Vivado is not supported for target floating point code generation. Please consider using Native Floating Point code generation option as a work around.

I'm having the same problem described by Samuel. Why do we have to install ISE, which was last released in 2014?

And when I use Native Floating Point code generation as a work around, I get the following error when I try to run simulation in Vivado:

• [XSIM 43-4187] File "/wrk/xhdhdnobkup2/mounicav/xsimsource/xsim_HEAD/data/vhdl/src/ieee_2008/float_pkg.vhdl" Line 45 : The "Vhdl 2008 Package Instantiation Declaration" is not supported yet for simulation.

Why does HDL Coder create code that results in references to VHDL 2008?

[Jonathan Howard]

And ISE doesn't support a lot of the newer devices, so why does HDL Coder still rely on it?

[Kiran Kintali]

HDLCoder does not rely on Xilinx ISE. If a user has installed the ISE software it continues to support the workflow with these tools as much as possible.

hi Samuel,

There is a special Note about Vivado in the help text:

Please note that Xilinx Vivado launcher for Windows is a '.bat' file. If you are providing full path to the launcher to hdlsetuptoolpath, make sure to provide correct '.bat' file.

Thanks
