A pin array can be created for a new or existing chip symbol.

On the Library Symbol toolbar, click Place > SMD Pad Array . In the SMD PAD ARRAY dialog, specify a Base Name, which is often a single letter, with or without a hyphen.

Ball Grid Array , a surface mount component with round soldering pads beneath the case.

On the Library Symbol toolbar, click Place > Pin Array . In the Place Pins dialog, specify a Base Name, which is often a single letter, with or without a hyphen.

On the Library Symbol toolbar, click Place > PTH Pad Array . In the PTH PAD ARRAY dialog, specify a Base Name, which is often a single letter, with or without a hyphen.

Brackets Brackets are used in array definitions int ai[]; in array subscripts n = ai[2]; and in string subscripts to access the individual characters of a string string s = "Hello world"; char c = s[2]; Parentheses Parentheses group expressions (possibly altering normal operator precedence), isolate conditional expressions, and indicate function calls and function parameters: d = c * (a + b); if (d == z) ++x; func(); void func2(int n) { ... } Braces Braces indicate the start and end of a compound statement: if (d == z) { ++x; func(); } and are also used to group the values of an array initializer: int ai[] = { 1, 2, 3 }; Comma The comma separates the elements of a function argument list or the parameters of a function call: int func(int n, real r, string s) { ... } int i = func(1, 3.14, "abc"); It also delimits the values of an array initializer: int ai[] = { 1, 2, 3 }; and it separates the elements of a variable definition: int i, j, k; Semicolon The semicolon terminates a statement, as in i = a + b; and it also delimits the init, test and increment expressions of a for statement: for (int n = 0; n < 3; ++n) { func(n); } Colon The colon indicates the end of a label in a switch statement: switch (c) { case 'a': printf("It was an 'a'\n"); break; case 'b': printf("It was a 'b'\n"); break; default: printf("none of them\n"); } Equal Sign The equal sign separates variable definitions from initialization lists: int i = 10; char c[] = { 'a', 'b', 'c' }; It is also used as an assignment operator.

The size of an array is automatically adjusted at runtime.

Signal fanout tries to add a via from each pad along the signal path, subject to design rule violations. Ball Grid Array (BGA) Autorouter has additional settings for elements and signals.

Syntax void sleep(int seconds); See also time() The sleep function delays the execution of an ULP program for number of seconds. sort() Function Sorts an array or a set of arrays . Syntax void sort(int number, array 1[, array 2,...]); The sort function either directly sorts a given array 1, or it sorts a set of arrays (starting with array 2), in which case array 1 is supposed to be an array of int, which will be used as a pointer array .

Use one of the following commands to place pads: SMD Pad PTH Pad SMD Pad Array PTH Pad Array In the Content Manager, right-click the footprint row and click Edit Description.

New Pattern can be used to create a rectangular array , circular array , mirror image or a random pattern of copied toolpaths.

If you chose the In Array (True Shape) option: Specify the Direction along which the copies are distributed.

This can be one Gate of a TTL component, one contact pair in a relay, or an individual resistor from a resistor array .

You can then rearrange them manually or automatically using Additive Arrange. In Array (True Shape) places copies at equal distances along a single axis.

In Electronics terminology, a Gate is a part of a Device that can be individually placed on a schematic (such as one transistor from a transistor array ). Gates that come with pins connected to several pads can't be swapped.
