title: SystemVerilog support of icarus (iverilog compiler)
body: <p>I am using <code>iverilog</code> on a Mac, and I have problem compiling some codes that include <code>always_ff</code> and <code>always_comb</code> blocks. ModelSim compiles those codes without any problem. Is it possible to configure <code>iverilog</code> so as to support <code>always_ff</code> and <code>always_comb</code> blocks, or they are just not supported by the compiler?</p>
