ABD - PSL Properties and Macros

PSL defines some simple path to state macros

• rose(X) ~~ means ~~ { !X; X }
• fell(X) ~~ means ~~ { X; !X }

Others are easy to define:

• stable(X) ~~ can be defined as ~~ { X; X } || { !X; !X }
• changed(X) ~~ can be defined as ~~ { X; !X } || { !X; X }

• onehot(X) ~~ can be defined as ~~ X is a power of 2
• onehot0(X) ~~ can be defined as ~~ onehot(X) || (X==0)
