I have migrated a design with a .bd into a new version (for example 2014.1).
When resetting and regenerating the .bd, a folder called "ipshared" appears in the directory where the "bd" folder is located.
What does this ipshared folder do?
The ipshared folder is a new feature added in 2014.1 to reduce the number of files that can explode with IP in an IPI (IP Integrator) design.
The files here are all static copies of files that are in the install area.
It helps to avoid unnecessary duplication of files, for example, multiple instances of block memory IP.
