* indicates a secondary parameter
 Allowed formats are return to zero (RZ) and non-return to zero (NRZ).
 Window type options are none (NONE), Lanczos (DEFAULT, ref ), Triangular (TRIANG), Hanning (HANN), Hamming (HAMM), and Blackman (BLACK).
SEQ. Specifies the symbol sequence. You can type the
sequence or load it from a text file. To load a sequence from a file, type
vfile("name_of_file") in the SEQ field. The file format is:
In the absence of a full path specification, place the file in the
\Data directory under the Cadence® AWR® Microwave Office® software installation
Symbols in multi-level signal formats are encoded as integers. In a four-level scheme, for example, symbols are represented by 0, 1, 2 and 3.
The data files with sequences can also be imported into AWR Microwave Office software to save the data with the project.
To use bit data from a file stored in AWR Microwave Office software:
Import the data file as a "Text Data File" type.
Assign a variable to the data file using the following syntax:
variable1 = DataFile("data_file_name")
variable1 is the variable name of your choice and
"data_file_name" is the name of the imported data file (the
name must be enclosed in quotes). This function saves the data in a matrix form.
Assign a variable to be the first column of the data in the first variable assigned in the following syntax:
variable2 = col(variable1,1)
variable2 is the variable name of your choice and now
stores the bit sequence assigned to the SEQ parameter.
With the exception of the SEQ parameter, PORT_ARBS is very similar to PORT_PRBS, which applies a random rather than user-specified sequence. See PORT_PRBS for information on the remaining parameters.
This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
