异步FIFO 顶层框图 图中传递的 wptr、rptr 均是 n+1 格雷码指针;两边的逻辑电路均使用“简单的比较策略”来生成 wfull 和 rempty ;waddr 和 raddr 可以由 6.4 节中第二种风格的电路直接生成;winc 、rinc 分别是写使能、读使能信号,只有使能信号有效,6.4 节电路里的递增加法器才会做加法,使能信号无

After a full power-down, the chip was woken up by a given event. At this point, some particular, retained status registers within the power management controller module containing a switchable power domain should be reset. In a non-power-aware environment, the reset was correctly applied to ...
Theassertstatement from SystemVerilog is supported in its most basic form. In module context:assert property (<expression>);and within an always block:assert(<expression>);. It is transformed to an$assertcell. Theassume,restrict, andcoverstatements from SystemVerilog are also supported. The same...
Additionally, although this directive is telling the synthesis tool to use the unused states as “don’ cares”, this t directive will sometimes make designs larger and slower than designs that omit the full_case directive. In module code4a, a case statement is coded without using any ...
In the present embodiment, power analysis system 100 analyzes the power dissipation level of an integrated circuit design specified at the register-transfer level (RTL) using a hardware description language (HDL), usually Verilog or VHDL. For example, as shown in FIG. 1, an integrated circuit ...
