Recommended Methodology for RTL and Gate Power Analysis
At time 50, rst_n=1 and set_n=0, but q remains at 0, and changes to 1 at time 55 when there is a rising edge of clk. Note that this problem is with RTL simulation; it has nothing to do with synthesis. In fact, the gate-level simulation works as expe...
Quartus II调用Modelsim的两种仿真形式为:1、RTL级仿真;2、Gate-level仿真。 以下内容均经过资料查证,详细如下: 理解方法一 当用quartus进行仿真时,分为功能仿真(al)和时序仿真(Timing); 当用Modelsim-Altera时,分为功能仿真(RTL)、综合后仿真(post-synthesis)和布局布线仿真(Gate-level)。其中,功能仿真又称为前...
By Durgesh Prasad, Jitesh Bansal and Madhur Bhargava The Unified Power Format (UPF) is used to specify the power intent of a design. Once written, the UPF file is applied at every stage of the design cycle — starting with the RTL, then the gate-level, and finally during place and rout...
Debugging an IC design at the transistor, Gate and RTL levels is often necessary to meet timing requirements and understand analog or digital behavior, yet the process itself can be a tedious one, filled with manual steps, therefore making it an error-pr
with the gate active when the G input is high. L1 and L3 are controlled by PH1, and L2 is controlled by PH2. A rising edge launches data from the latch output, and a falling edge captures data at the latch input. For this example, consider the latch setup and delay times to be ze...
FPGA是现场可编程门阵列(Field Programmable Gate Array)的缩写。FPGA是一种集成电路,包含固定数量的逻辑块,可在IC制造后进行重新配置(而ASIC的内容和布局必须在制造前确定)。从历史上看,FPGA不能包含ASIC那么多的功能,只能以较慢的时钟速度运行,这是RTL级设计时的重要考虑因素。FPGA技术的最新进展显著缩小了FPGA和ASI...
ASIC或者FPGA设计就是把一个想法或者概念转换成物理实现的过程。这篇文章讨论了HDL编码风格所造成的RTLGate-level仿真的不一致的几种情况。 它的一个基本的判定规则是,符合以下两种情况的编码风格是坏的编码风格。 提供给HDL仿真器的关于设计的信息不能传送给综合工具 ...
