Hierarchical clock gating
WebWhen the hierarchical clock-gating feature is enabled, and more than one clock domain contains a view to a register that is visible in the programmers model or an access point, an extra clock domain is added to the interconnect. This clock domain distributes accesses … Webi have tried to solve this problem by writing down clock gater ( latch + and gate) by designing them from altera standard cells : module db_altclkctrl0 ( ena, inclk, outclk); input ena; input inclk; output outclk; wire clk_en_int; latch latch_i0(ena, ~inclk, clk_en_int); and and_i0(outclk, clk_en_int, inclk);
