Half-Rate Clock Not Connected When Clock Sharing is Enabled - Half-Rate Clock Not Connected When Clock Sharing is Enabled Description If you generate a memory controller with the High Performance Controller II and Multiple Controller Clock Sharing options enabled in SOPC Builder, the half-rate clock is not connected. This issue affects all designs that use the high-performance controller II architecture with the Multiple Controller Clock Sharing option enabled in SOPC Builder. The internal half-rate bridge for the sharing PLL controller does not function. Resolution To connect the half-rate clock, perform the following steps: Edit the sharing PLL controller top-level file to include the half-rate clock input port as in the following example: Verilog HDL module <variation name> ( sys_clk_in, sys_half_clk_in, soft_reset_n, input sys_clk_in; input sys_half_clk_in; input soft_reset_n; .sys_clk_in(sys_clk_in), .sys_half_clk_in(sys_half_clk_in), .soft_reset_n(soft_reset_n), VHDL ENTITY <variation name_master> IS PORT ( sys_clk_in : IN STD_LOGIC; sys_half_clk_in : IN STD_LOGIC; soft_reset_n : IN STD_LOGIC; COMPONENT <variation name> _controller_phy PORT ( sys_clk_in : IN STD_LOGIC; sys_half_clk_in : IN STD_LOGIC; soft_reset_n : IN STD_LOGIC; sys_clk_in => sys_clk_in, sys_half_clk_in => sys_half_clk_in, aux_full_rate_clk => aux_full_rate_clk, Edit the SOPC top-level file to connect the half-rate clock from the source to the sharing controller as in the following example: Verilog HDL <variation name> the_ <variation name> ( .soft_reset_n (clk_0_reset_n), .sys_half_clk_in ( <variation name_master> _aux_half_rate_clk_out), .sys_clk_in ( <variation name_master> _phy_clk_out) VHDL component <variation name> is port ( -- inputs: signal soft_reset_n : IN STD_LOGIC; signal sys_half_clk_in : IN STD_LOGIC; signal sys_clk_in : IN STD_LOGIC; the_ <variation name> : <variation name> port map( soft_reset_n => clk_0_reset_n, sys_half_clk_in => out_clk_ <variation name_master> _aux_half_rate_clk, sys_clk_in => internal_ <variation name_master> _phy_clk_out This issue will be fixed in a future version.
