Are complementary outputs available in the 22V10?

解决方案

Whether the output is registered or combinatorial, you may choose from either true or complementary outputs. 

 

To use the complementary output in ABEL, use the "invert" attribute. 

 

For example:  

 

MODULE top 

 

O1 pin istype 'reg, invert'; 

 

AR, CLK, DIN pin; 

 

EQUATIONS 

 

O1.d = DIN; 

O1.AR = AR; 

O1.CLK = CLK; 

 

END 

 

You can confirm the use of the "invert" output by looking at the .ann file and checking for 

 

O1 PIN 21 istype 'invert';
