modelsim integer port type representation

thx for the reply Tricky

but why in modelsim-altera simulation wavesform i can't see the "c" integer type port as a vector of 5 elements like in quartus 2 simulation ?

modelsim-altera represent this "c" port declared as integer in an object called "c" (just 1 element) and an other object called "ww_c" which is a vector of 5 elements

what the "ww" mean in "ww_c" in modelsim ??
