"The instructor was clearly an expert, and extremely good at presenting the material."

Welcome

Sutherland HDL provides expert training workshops on Verilog and SystemVerilog. We periodically hold open enrollment public workshops at various locations across the nation. For your convenience, you may also request that we present our workshops on-site at your company.

 

 

 

Sutherland HDL training workshops help engineers become true Verilog and SystemVerilog wizards! Workshops are developed and presented by engineering experts with many years of experience in design and verification. Our design-oriented workshops emphasize creating models that use logic synthesis correctly and avoiding coding gotchas. Verification-oriented workshops emphasize writing assertion-based, constrained random, object-oriented testbenches. Sutherland HDL has trained thousands of engineers throughout the United States, and in Canada, England, Germany, Japan, Malaysia, and Hong Kong.

Verilog and SystemVerilog Quiz and Tips

The example below models a flip-flop with asynchronous set/reset logic (active low).  The model synthesizes correctly, but there is a corner case where simulation results are incorrect.  What is the corner case?

always_ff @(   posedge clk
            or negedge rst_n     // active-low reset
            or negedge set_n     // active-low set
           )
  if (!rst_n)           // reset has priority over set
    q_out <= ’0;        // reset all bits to zero
  else if (!set_n)
    q_out <= ’1;        // set all bits to one
  else
    q_out <= data_in;   // d input assignment
