General Description: How do I target a CoolRunner CPLD using VHDL/Verilog?
ソリューション
CoolRunner CPLDs are supported by Xilinx Synthesis Technology (XST). XST synthesizes VHDL and Verilog designs and produces an EDIF file of the design. The EDIF file output from XST can be imported into XPLA Professional for compilation and fitting into a CoolRunner CPLD. XST is available free-of-charge as part of WebPACK from http://www.coolpld.com/products/software/webpowered.htm. An applications note will be available soon that provides step-by-step instructions for using XST to target a CoolRunner CPLD.
XPLA Professional currently supports Verilog design entry. When the integration of the Coolrunner into Xilinx WebPACK is complete, the XPLA Professional design entry support will no longer be available.
VHDL files are not supported as a project source file in XPLA Professional. Again, customers are encouraged to synthesis Verilog designs with XST.
For those customers that have synthesis tools from Synplicity, Exemplar, Synopsys, or Viewlogic, XPLA Professional supports EDIF flows from these vendors.
