Is there a way to add a constraint specifying the max delay between two points (without the clock skews, etc taken into consideration)? I understand that in many cases, taking the skew into consideration is desirable, but I do have a case where I simply don't care about the clock skew...
当飞行员接收到上传的CPDLC信息“SET MAX UPLINK DELAY VALUETO [XX] SECONDS ”时。1、无论飞机是否具有延迟监视功能,根据飞机设备的提示,飞行员应积极回应ATC,如使用ACCEPT或者ROGER。 飞行员必须对“SET MAX UPLINK DELAY VALUE TO [XX] SECONDS”信息做出响应,以避免在系统中打开未应答的CPDLC信息。这也适用...
We have a reset synchronizer with very high final fanout. The synchronized reset signal typically ties to the R, or sometimes the P, input of the destination FFs. Due of the high fanout and wide distribution (anywhere in the SLR) of the reset signal, t
Your use of set_max_delay is unusual and can lead to problems. Please read pages 130-137 of UG903(v2021.2) for a good description of set_max_delay. In particular, note the warnings about path segmentation caused by improper use...
Delay calling connection.set_max_concurrent_uni_streams() and connection.set_receive_window() to when we know we've accepted the connection. Avoids a short window where the peer could start transmi...
set_max_delay -from spi_master_wrap_u|spi_tx_u|tx_sck_o|q -through spi_master_wrap_u|sck_o~0|combout -to m_spi_ck_o~output|i 2.100 Is there any problem for the constarins or it's not correct to use these constrains. Would someone will...
Without looking at your design, if these clock domains are asynchronous, you should use set_clock_groups to simply cut all paths between them. By using set_max[min]_delay, the tool will still analyze timing on paths that go between these clock domains and you see what's...
Another (probably better) way could be to use a phase shifted clock from a PLL. Enabling physical synthesis may also help, but I would generally prefer a solution where the timing constraints are used to balance unavoidable routing delays rather than forcing a huge imbalance ...
The setup relationship is what the interface needs to meet timing, and the -max value is how much of this is used externally. Whatever isn't used externally is allowed for the FPGA. So if your setup relationship is 4ns and the -max is 1.5, that means the FPGA has 2.5 to work. ...
