XST

基本解釋

WARNING:Xst:1778 - Inout is assigned but never used.
這些信號(hào)是用了的,,,為什么會(huì)出現(xiàn)這個(gè)警告啊???/?
WARNING:Xst:916 - u3031_v.v line 40: Delay is ignored for synthesis.
請(qǐng)問(wèn)是不是這個(gè)軟件本身不能用延時(shí)還是其它原因呢？
In the XST group, same changes in FIB, t-PA and PAI were shown but with APC increased, and PT and APTT unchanged.
血栓通組治療后FIB水平下降，t-PA活性增加，PAI活性下降，APC活性增加，而PT及APTT無(wú)顯著變化。
ERROR:Xst:1225 - Loop has iterated 64 times. Use "set -loop_iteration_limit XX" to iterate more.
是不是程序中的循環(huán)數(shù)目還有限定阿，如果要設(shè)置的話在什么地方設(shè)置呢？
ERROR:Xst:867 - ../../src/hex2bcd.v line 24: Operator / is only supported when the second operand is a power of 2.
我把除法、求模運(yùn)算的第二個(gè)操作數(shù)改為2的冥如“8”，綜合就可以過(guò)了。難道只能對(duì)2的冥進(jìn)行除法求模運(yùn)算？
