Video Pattern Generator Signals
Table 3-8: Video Pattern Generator Top Level Signals
Table below lists the input signals for the video pattern generator. The listed signals are exported at the top level of
the design example. Other signals—that are not exported—connect within the design example entity.
Signal Width Direction Description
pattgen_tx_std 2 Input Transmit video standard.
• 00: SD-SDI
• 01: HD-SDI or HD-SDI dual link
• 10: 3G-SDI level B
• 11: 3G-SDI level A
pattgen_tx_format 4 Input Transmit video format.
• 0000: SMPTE259M 525i
• 0001: SMPTE259M 625i
• 0100: SMPTE274M 1080i60
• 0101: SMPTE274M 1080i50
• 0110: SMPTE274M 1080p24
• 0111: SMPTE296M 720p60
• 1000: SMPTE296M 720p50
• 1001: SMPTE296M 720p30
• 1010: SMPTE296M 720p25
• 1011: SMPTE296M 720p24
• 1100: SMPTE274M 1080p30
• 1101: SMPTE274M 1080p25
• 1110: SMPTE274M 1080sF24
• Others: Reserved for future use
pattgen_dl_mapping 1 Input Dual link mapping. Set to 1 for HD-SDI dual link
and 3Gb transmit video standard only.
pattgen_ntsc_paln 1 Input Transmit rate.
• 0: PAL (1) rate. For example, 1080p30
• 1: NTSC (1/1.001) rate. For example,
1080p29.97.
This input ignores all SD video formats (525i, 625i)
and certain HD video formats that do not support
NTSC rate (1080i50, 720p50, 720p25, 1080p25).
pattgen_bar_100_75n 1 Input Generate color bars.
• 0: 75% color bars
• 1: 100% color bars
