If I double-click the CLB, then it brings up ViewBlock,
why not edit block?
This is the current behavior of FPGA Editor. Double
clicking in the array window is an alias of the
"post block" and editblock button on the user tool bar
is mapped to the editblock command. While the post
block command can be operated on a site or a
component, the ediblock command can only operated
on a component.
