This is a publication style that permits poor photocopies to identify big junction dots from dots of stray carbon on old machines. It resembles the output from TinyCad. Notice it omits some of the useful design info like RefDes ,PN , value, tolerance. I like the big dots too. I used to have HP software like this with rubber band autofit connections that ...

Omni Graffle shouldn't take that long, there are tools in the software to overcome some of the issues you mentioned. http://techjournal.318.com//wp-content/uploads/2009/12/omnigraffle-tips-pub.pdf has some of them, and we built an applescript that counted up all of the elements of our drawing for easier planning. An example of the script that we wrote is ...

you have three dots in your bus name. you should have two. e.g. Sense[1...8] should be Sense[1..8] http://techdocs.altium.com/display/ADRR/Sch_Obj-Bus((Bus))_AD

This question comes up in both the schematic entry phase, and also in the PCB layout phase. I'll explain both cases. These answers are for version 16.6 (S025), but I expect they'll work for your version. Schematic Entry In this case, general Grid settings can be found in the toolbar, by clicking on Options -> Preferences. In the screen that comes up, ...

It's a flexible connection of some kind. In this drawing, it is likely to represent a trailing or reeling cable (I will explain this a bit more below.) Supporting my claim - from AS1102.3 Graphical symbols for electrotechnical documentation - Part 103: Conductors and connecting devices, we have: Note AS1102 is based on IEC 617 Graphical symbols for ...

A list I use for Multisim: Do all tantalum caps on rails have at least ~20% overhead? No 25V caps on 24V lines? Are there bypass caps on the power rails of every chip? Even the ones that don't look like chips, like regulators? Are there filters on every transistor gate/base? Even the ones in processors? Are there filters on A/D converter pins? Are there ...

The purpose of a schematic, generally speaking, is to show those aspects of something which are most relevant to understanding it, at the expense of changing details which are less relevant. For electrical schematics, the biggest thing that's omitted is an accurate sense of physical layout, but schematics may also omit certain forms of "regular" wiring (as ...

Schematic A schematic shows connections in a circuit in a way that is clear and standardized. It is a way of communicating to other engineers exactly what components are involved in a circuit as well as how they are connected. A good schematic will show component names and values, and provide labels for sections or components to help communicate the ...

What you got is a footprint for a teensy connector. There is no information in that about the teensy itself.

1: the capacitor circled in red is optional, that is why there is a jumper link there. According to page 7 in the pin description tables: "The regulator requires a decoupling capacitor of 100 nF typical, which is connected from CAP/2.5V to DGND" Therefore, just use the 100nf cap. 2: AS before, in the pin function table page 8 the COMP pin needs that cap ...

The pins that aren't listed in the schematic are probably not connected. They may be disconnected and only present for compatibility with other connectors in the family that use them, they may be there as mechanical supports, or they may connect to internal hardware that isn't shown in the schematic! The only thing that you can safely assume, though, is that ...

The other 2 pins are usually normally-closed connections for the pins adjacent to them; plugging in a jack moves the adjacent pins away from them, breaking their connection. They are used either as sense or to shunt audio to internal speakers when no headphones are plugged in. OTOH, the fact that they aren't given in the schematic may mean that they are only ...

Bisg is an INPUT signal not an INOUT despite the fact that it has other uses (driving segment G on the top level). To see this; reflect that NOTHING in your component actually drives BISG. So your component is regarded as driving it with an undefined initial level; that is, 'U', and the combination of that 'U' with any external driving level is - as ISIM ...
