Notes/Equations
- This model is used to generate the transport channel signal source with TFI input.
- The transport channel source serves as a bit source, the rate of which is determined by the DynTFSet parameter. The content is determined by DataPattern, which offers five data patterns.
DynTFSet consists of transport block size and transport block set size groups. The transport block set size is a multiple of transport block size. For example, if a transport channel has a transport format set:
The DynTFSet should be set as "10 20 10 40". DataOut will output 40 tokens (the maximum transport block set size) each firing.{10 bits, 20 bits}; {10 bits, 40 bits}
- If the data pattern is 8-bits repeating, the bits to be repeated is set by RepBitValue. For example if the RepBitValue is set as 0 x 7a, the bit sequence 0, 1, 1, 1, 1, 0, 1, 0 will be output repeatedly.
If the data is from user-defined file, the file name is specified by UserFileName. The designer can edit the file with any text editor. The separator between bits can be a space, comma, or any other separator. If the bit sequence is shorter than the output length, output data will be repeated.
