# Usage model

## State dependent power analysis mode

### MCMM power analysis usage model

Please check regression case "qa_report_power_analysis_mcmm1" 

Method 1:

```

current—mcmm {func—ss—rcmax scan—ff—rcmin} 

compute—timing

report—power—analysis -working—scenario func—ss—rcmax 

report—power—analysis -working—scenario scan—ff—rcmin

```

Method 2:

```

current—mcmm {func—ss—rcmax scan—ff—rcmin} 

compute—timing

set—working—scenario func—ss—rcmax 

report—power—analysis      

set—working—scenario sccan—ff—rcmin 

report—power—analysis

```

## Vector based power analysis:

Below will align with reference behavior:

```

髻 align all the vcd time to 江ero set—app—var pow vcd—align true

髻 other option:

align—vcd test.vcd -start—time 123

髻 select power window

report—window—power -window—si江e xxx -step—si江e xxx -module—map—file xxx 

report—window—power -window—si江e xxx -step—si江e xxx -single—vcd—file xxx

```

## Power annotation flow: (Under development) ref ticket #7955

```

髻 convert ref power file to VP readable command 

convert—emir—power xxx xxx.tcl

髻 in the xxx.tcl we have a set of command which has:

set—emir—power cellName -frequency freq -toggle—rate tr -leakage—power lp -switching—power sp -int ernal—power ip

髻 later we will use the command to derive IR ...

```

## To change cap mode mode:

```

髻 default is cap range, which is to correlate PXXX 

set—app—var cap—usage rangelrise—fallldefault

```

## Power param

1. effsw_use_initial default: false 

`false: use condition number calc effse `

`true: use initial way calc effsw`

2. power_mode default: 0

`0: sdp mode`

`1: avg_fast mode`

3. trans_use_max default: false

`false:rise and fall internalpower use themself max trans to lookup` 

`true: rise and fall internalpower use max trans to lookup`

4. result_calc_way default: 0 

`0: worst val * arcNum`

`1: worst(relatedPinA)*arcNum(relatedPinA) + worst(relatedPinB)*arcNum(relatedPinB) ... worst(relatedPinN)*arcNum(relatedPinN)`
