    Does anybody know when Xilinx is planning to add SystemVerilog support to XST. At this point pretty much all 3-rd party IP cores I encounter with are using SystemVerilog. It's counterproductive for me (and perhaps other customers) to port all the nice SystemVerilog language structures back to Ver...

Virtex Primitive Support

    http://www.csit-sun.pub.ro/courses/Masterat/Xilinx%20Synthesis%20Technology/toolbox.xilinx.com/docsan/xilinx4/data/docs/xst/virtex8.html
    XST allows you to instantiate Virtex primitives directly in your VHDL/Verilog code. Virtex primitives such as MUXCY_L, LUT4_L, CLKDLL, RAMB4_S1_S16, IBUFG_PCI33_5, and NAND3b2 can be manually inserted in your HDL design through instantiation. These primitives are not optimized by XST and will be available in the final NGC file.

    XST only supports sequential blocks. Within these blocks, the statements are executed in the order listed. Parallel blocks are not supported by XST. Block statements are designated by begin and end keywords, and are discussed within examples later in this chapter. Modules In Verilog a design component is represented by a module.

    Oct 28, 2009 · XST synthesizes this with no errors, warnings, or infos. The module is totally clean. Even so, the netlist it produces gives value a constant output of 13. Let’s see Xilinx support try to squirm their way out of this one. This seems like a bug to me. At any rate, I have to give up on a pure Verilog solution to a fixed point library. Time to ...
