The present disclosure discloses a circuit layout routing method and apparatus, a device, a storage medium, and a product, and relates to the field of micro-nano processing technologies. The method includes: obtaining position information of at least one routing point in a circuit layout from routing planning information of the circuit layout (41); calculating, based on the position information, a turning starting position and a turning radius corresponding to each of the at least one routing point (42); and generating a routing path through the at least one routing point based on the turning starting position and the turning radius, the routing path turning at the turning starting position with the turning radius (43). The foregoing solution expands an applicable scenario of an automatic routing algorithm.
