In the Legacy Schematic File Format document, the following pin shapes are listed:
Line None(default)
Inverted I
Clock C
Inverted clock CI
Input low L
Clock low CL
Output low V
Falling edge clock F
Non Logic X
Meanwhile, the latest S-expression format documentation lists the following pin styles (=shapes):
line
inverted
clock
inverted_clock
input_low
clock_low
output_low
edge_clock_high
non_logic
When comparing the old and new pin styles, the old “Falling edge clock” and the new “edge_clock_high” do not seem to match.
So here’s my question.
Q1)
Does “edge_clock_low” not exist in the new format?
I think “edge_clock_low” would match “Falling edge clock”.
Q2)
In the new format, clock and “edge_clock_high” have different pin images, but do the terminals have the same meaning?
