Get the n1 field from a ringosc3.
(ringosc3->n1 x) → n1
This is an ordinary field accessor created by defprod.
Function:
(defun ringosc3->n1$inline (x) (declare (xargs :guard (ringosc3-p x))) (declare (xargs :guard t)) (let ((acl2::__function__ 'ringosc3->n1)) (declare (ignorable acl2::__function__)) (mbe :logic (b* ((x (and t x))) (sig-path-fix (cdr (std::da-nth 0 x)))) :exec (cdr (std::da-nth 0 x)))))
Theorem:
(defthm sig-path-p-of-ringosc3->n1 (b* ((n1 (ringosc3->n1$inline x))) (sig-path-p n1)) :rule-classes :rewrite)

Theorem:
(defthm ringosc3->n1$inline-ringosc3-equiv-congruence-on-x (implies (ringosc3-equiv x x-equiv) (equal (ringosc3->n1$inline x) (ringosc3->n1$inline x-equiv))) :rule-classes :congruence)
