Vivado HLS - RTL export results in "@E [IMPL-28] Failed to generate IP" or "@E [IMPL-4] 'xtclsh' cannot be found. Please check your PATH variable."

Description

RTL export with format of IP-XACT results in the following error:

@I [IMPL-8] Exporting RTL as an IP in IP-XACT.
'vivado' is not recognized as an internal or external command,
operable program or batch file.
@E [IMPL-28] Failed to generate IP.

RTL export with format of Pcore for EDK results in the following error:

@E [IMPL-4] 'xtclsh' cannot be found. Please check your PATH variable.

Solution

To perform RTL implementation, Vivado HLS must invoke either Vivado or ISE design tools; therefore, the Xilinx tools path must be known. A few ways to achieve this are explained below:

Create a project with Vivado or ISE design tools and import the RTL source files from the Vivado HLS project. The RTL outputs or IP core will be available in the <project>/solution<#>/impl folder.
Alternatively, invoke Vivado HLS from the Vivado or ISE command line by browsing to the <Xilinx_installation_directory>\Vivado_HLS\<xilinx_version_number>\bin\vivado_hls
Setup the Xilinx environment as described in (Xilinx Answer 39339) before invoking Vivado HLS.
