title: Verilog linting tools?
body: <p>What are some good linting tools for verilog?  I'd prefer one that can be configured to either handle or ignore certain vendor specific primitives like LUT's, PLL's, etc.</p>
  
  <p>I recently tried verilator-3.810, but out of the box it needs a little help with the primitives.</p>
  
  <p>So what (linting) tools do you use to deal with the not-so-strict syntax of verilog?</p>
