    <p>We are looking at moving some code into a CPLD or FPGA in order to make it faster. I have worked with Xilinks and their suite of tools before, but for some reason it was decided that we'd use Altera this time around so I am trying to get used to Quartus II.</p> <p>In particular, I am looking for a way to explicityly assign pins to the chip I am using. In Xilinx, I'd edit the netlist file but I can find no such thing in Quartus. There <em>is</em> a program (Assignments => Pin Planner) that does this, but it has a clunky GUI and I'd far prefer to edit the pins in a text editor, so my twofold question is</p> <p>A: How do I find the file that stores the pin assignment? It's not listed under my files in the project navigator but the pins I've assigned in Pin Planner stay from session to session so they must be stored <em>somewhere</em>.</p> <p>B: Is this a horrible idea?</p> <p>IDE is Quartus II 10.1 Development kit is MAX II Development Board Language is VHDL</p> <p>EDIT: Right now, I've run into the problem that I'm trying to interface with the Dev Kit through USB. I'm making a serial data receiver on it and have given it a Data In pin. The Dev Kit has a USB receiver so I'm trying to map din to whichever pin the USB connector is on. According to a file I have (rm_maxII-develop_board-rev1.pdf) the USB connector is on "Board Designation U13" but when I go into the Pin PLanner and try to assign that, there is no PIN_U13. I suspect this is an error in the pdf, rather than in Pin Planner but seing as I've never worked with Altera products before, I'm very confused.</p>

    2. COI did - slightly before I read about Overmapped and figured that'd be a better place for it. What's your user name on Overmapped? I see no replies from Amigable Clark Kant over there.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
