Hi, the change for Mantis 1330 includes the following example, and it is implemented in Draft 3: interface #(parameter WIDTH=8) PBus; // A parameterized bus interface logic req, grant; logic [WIDTH-1:0] addr, data; modport phy(input addr, ref data); endinterface module top; PBus #(16) p16(); PBus #(32) p32(); virtual Pbus V8; // legal declaration, but no legal assignments virtual Pbus #(35) V35; // legal declaration, but no legal assignments virtual Pbus #(16) v16; virtual Pbus #(16).phy v16_phy; virtual Pbus #(32) v32; virtual Pbus #(32).phy v32_phy; initial begin v16 = p16; // legal- parameter values match v32 = p32; // legal- parameter values match v16 = p32; // illegal - parameter values don't match v16 = v32; // illegal - parameter values don't match v16_phy = v16; // legal assignment from no selected modport to selected modport v16 = v16_phy; // illegal assignment from selected modport to no selected modport v32_phy = p32.phy; //legal assignment from no selected modport to selected modport v32 = p32.phy; // illegal assignment from selected modport to no selected modport end endmodule The next-to-last assignment and its comment seem to me to be inconsistent: v32_phy = p32.phy; //legal assignment from no selected modport to selected modport Should it be either v32_phy = p32; //legal assignment from no selected modport to selected modport OR v32_phy = p32.phy; //legal assignment from selected modport to selected modport ?
