11.8.3. Changing the Reset Trigger of the Default Traffic Generator
If you prefer to have a level-sensitive, typically active-low reset signal as was common with earlier device families, you can invert the design example reset signal by making the following RTL changes to the ed_synth.v file:
- Add the following two lines in the wire declaration section:
wire reset_invert; assign reset_invert = !local_reset_req;
- Where the reset block is instantiated, change the local_reset_req to connect to the inverted reset signal called reset_invert, as follows:
ed_synth_local_reset_combiner local_reset_combiner ( .clk (emif_fm0_0_pll_ref_clk_out_clk), .reset_n (emif_fm0_0_pll_locked_pll_locked), .local_reset_req (local_reset_req), .local_reset_req (reset_invert), .local_reset_req_out_0 (local_reset_combiner_local_reset_req_out_0_local_reset_req), .local_reset_done (local_reset_done), .local_reset_done_in_0 (emif_fm0_0_local_reset_status_local_reset_done) );
In addition, it is a good idea — though not mandatory — to also run analysis and elaboration, to help show project structure and verify assignments.
