Commercial "vendor neutral" tools do exist, Synplicity was a public company which sold such tools for several years before branching into proto board hardware sales and then being acquired by Synopsys [1]. Their tools for synthesis, partitioning and debug are still available [2] and strong sellers to both Altera and Xilinx FPGA developers.
