+% baselen is relative to pgfcirc@Rlen as ever; scaled if the class says so.
+% the value of 0.4 is the standard pin distance for a port with height=num pins
+% and matches the chip distance
+\ctikzset{ieeestd ports/baselen/.initial=0.4}
+% these are in term of baselen; width depends on height (fixed proportions)
+\ctikzset{ieeestd ports/height/.initial=2}
+\ctikzset{ieeestd ports/pin length/.initial=0.7}
+% the standard "not" circle should be 1/6.5 of height (diameter);
+% so radius/baselen=1/3.25/2 --- using 0.1 and no scaling is as a pole
+\ctikzset{ieeestd ports/not radius/.initial=0.154}
+\ctikzset{ieeestd ports/not radius fill/.initial=1}% change ony if you know why
+% the suggested xnor distance is is 1.24, so 1.25/3.25/2
+% xor/xnor leads go full in in IEEE; let this be optional
+\ctikzset{ieeestd ports/xor bar distance/.initial=0.192}%
+\ctikzset{ieeestd ports/xor leads in/.initial=1}%

+% base size of a small external schmitt symbol

+% we are using the same /tikz/number inputs than the legacy ports
