    In Encounter, How to create shape of floorplan

    I want to create L shape in encounter. How can I do that by command in encounter. (p/s: By Guide in Encounter, I can do it but it's so complicated. My way is Specify floorplan-> Cut rectilinear)

    Block Diagram for mobile phone's portable bank power

    This is good idea. However, I haven't understand clearly about inputs and output of circuit. charging battery only operates when having power supply, besides, when circuit have load (the stepup circuit works), these leds will show level of Liion. - - - Updated - - - dear, It seems to photo...

    Block Diagram for mobile phone's portable bank power

    That's a good idea- ligth the LED use for charging circuit and stepup circuit. However, how can I connect them? button, switch circuit,... in a board

    Block Diagram for mobile phone's portable bank power

    I absolutely agree with you. Now, I'm concentrating on detail block diagram for portable power bank. I'd like to indicator led only "on" when charging battery or discharging to cell phone. And charging circuit and step up circuit operates only pressing a button.

    Block Diagram for mobile phone's portable bank power

    About basics, input is solar cell or 5 Vdc USB; and output is 5V; current is approximate 1A. Besides, i have Li ion battery.

    INL simulation in Cadence

    Virtuoso 6.1.4 is I'm using. They give example but I applied for my waveforms, results weren't as shape as example. https://obrazki.elektroda.pl/7473405000_1474617896.png https://obrazki.elektroda.pl/5066858000_1474617929.png If we can simulate in Calculator, it ill save more time.

    INL simulation in Cadence

    Thank you for documents. It 's very useful. However, I'd like to know about function "inl" in Calculator; how set up parameters? https://obrazki.elektroda.pl/8516975900_1474526036.png

    the perfect circuit to indicate battery level

    https://obrazki.elektroda.pl/5083297700_1474172432.png The photo show the simple circuit. I'd like when having load, indicator operates.

    the perfect circuit to indicate battery level

    Thank for your opinion. Because I design this circuit in first time, I can only give a range for specifications. - supply voltage: 3-4.2V ( voltage of Li ion). - current when indicator: 8-10mA. - currenr when no indicator ( battery hasn't load): less than 0.3mA.

    the perfect circuit to indicate battery level

    My circuit is to display discharge. Li ion battery is discharged to another circuit. So: Firstly, minimum current is necessary. Secondly, It is really better if indicator circuit is only operates when Li ion is connected to discharge.

    the perfect circuit to indicate battery level

    Hi all, My purpose is show captivity of battery in external backup battery. So, saving current is very important. If I use circuit which Bradtherad posted, is it best way?
