发帖数: 331 | 1 You need to have simulation library .v file with .lib(such as tsmc65lp.v).
After synthesis, you will get .sdf file and you can put
$sdf_annotate(....) in your verilog testbench for simulation.
But I suggest you run STA(PrimeTime) or Formal checking instead as gate
level simulation is time consuming and not so effective in coverage.

发帖数: 331 | 2 What kind of non-linear circuit? Normally the special simulation engine are
used for RF simulation such as Mixer, Oscillators etc.
从频域进行 Harmonic balance simulation, it is solving KCL/KVL in frequency
domain, in hspice, you can use .hb .hbac etc and ADS is strong in this.
Aother type analysis for non-linear RF circuit is shooting newton, in hspice
use .sn .snosc(for oscillators) .snnoise etc., in Cadence use PAC, PSS(
periodical steady state). Golden gate is good too. Popular for switch cap

发帖数: 757 | 3 我不太知道你说的corner simulation是什么意思。不过我猜吧
monte carlo: 举例来说，如果你有两个电阻的串联电路，每个电阻的误差遵循一个
比如高斯分布，那你可以用数学方法求出串联后的分布。但是实际系统很复杂。
monte carlo就是用实验的方法求这个分布。具体是比如1000次机会，对于每个电阻
按它自己的分布随机产生数，然后看总体的系统和的分布。clear?
corner simulation我猜就是想办法找corner condition，比如上面这个例子的
两个电阻都是巧合在分布上的最小值，或者最大值。 |

发帖数: 231 | 6 0.0003% Joint Probability can be simulated as it is. I guess the tricky
point in the problem is that since you simulated so many times (1000) with
so small joint probability, it should be the same as independent(0% joint
probability). So the simulation results are much the same. |

发帖数: 242 | 8 问题相对简单，就是做一个NON－RANDOMIZED TREATMENT GROUP COMPARISON ON
SURVIVAL OUTCOME。这里既然非随机，那么TREATMENT GROUP 和COVARIATES是相关的，
实际中做COX MODEL时加GROUPING VARIABLE 的同时也要ADJUST COVARIATES AS
CONFOUNDERS。
我现在不是很清楚具体SIMULATION步骤，文献有一篇：
１。 SIMULATION X FROM condition distribution function F（X｜GROUP）。这个X
的分布FUNCTION比较复杂。
２。 SIMULATE SURVIVAL TIME LOG（T）=B１＊X+ERROR。这里ERROR 是EXTREME VALUE
DISTRIBUTION。
但这里X只是一个单变量，而我希望有多个变量。虽然我知道X DEPENDENT ON GROUP，
但为什么不在LOG（T）后面加上GROUP。比如LOG（T）=B０＊GROUP+B１＊X+ERROR？
不知道是否下面是否可行：

ABSTRACT:
Computational tomography-based scans contain information that can be used to
reconstruct a human vertebra and, along with densitometry studies, help in
the understanding of bone failure. An in vivo digital model of a human lumba

It’s amazing that humans exist. For life to start on Earth, we needed
everything to be just right. We’re the perfect distance away from the Sun,
the atmosphere has the correct composition, and gravity is just powerful
enough. And though there may be many other planets with those conditions,
life gets even more impressive when you widen your perspective beyond Earth.
If some cosmic factor like dark energy were even a little stronger, life
probably wouldn’t exist, either ... 阅读全帖 |

People have long exchanged ideas of a god as a designer of the world. Some
imagine one particular god as a bearded man in the clouds, but simulation
theory says that that god (or any other) may instead be a bespectacled
programmer hunched over a keyboard.
As we’ve established, a programmer can create worlds out of simple binary.
The only question then is why the programmer would encode within us the
desire to worship our creator, a key part of most religions.

The problem is, my monitor is 1920x1280. So the simulated iphone is too long

In the past the default was ip4s. So it's not a problem to me.
