“IOSTANDARD”是电气标准,如LVCMOS18、LVCMOS12等等。 set_property IOSTANDARD[get_ports ] (3)引脚驱动能力设置 set_property DRIVE <2 4 6 8 12 16 24> [get_ports ] (4)引脚抖动设置 set_property SLEW[get_ports ] (5)引脚上拉设置 set_property PULLUP true [get_ports ] (6)引脚下拉设置 set_...
set_property DRIVE 16 [get_ports led1] 1. 6.输出(双向)引脚转换速率slew rate可以设置为快fast和慢slow。默认为slow。 将led1所在输出引脚转换速率设置为快: set_property SLEW FAST [get_ports led1] 1.
Also, when we drive the DUT’s input ports, we also need to use data type from vanilla Scala. For the Boolean type, it means we should use “true/false” instead of “True/False”, and the syntax would be like dut.io.srst #= false ...
Drive Strength:对于LVCOMS和LVTTL标准的输出缓冲器如OBUF,OBUFT,IOBUF等,可以设置需要的驱动强度,相同的标准在不同的I/O类型可设置的驱动强度也不同,如下图 拉动类型:输入缓冲器IBUF,三态输出缓冲器OBUFT和双向缓冲器IOBUF可以微上拉电阻,微下拉电阻或是微保持电阻,可以通过Pull type来设置 ...

DOUT_CSO_B never persist. Any I/O pins that persist cannot be used as I/O in the user design. Use the CONFIG_MODE constraint to reserve the correct pins during implementation of the design. Persisted I/O use the general-purpose I/O standard default of LVCMOS, 12 mA drive, Slow slew...
