306 - Can I program ispPAC-POWR or ispClock products with the Lattice USB ispDownload cable?
Yes. User can use the following tools with Lattice USB ispDownload cable to program:
1. PAC-Designer: -PAC-Designer version 4.98 or later does support the USB programming cable with ispPAC-POWR or ispClock devices. Previous versions of PAC-Designer did not support programming with the USB cable.
2. ispVM System:
- ispVM System version 13.01 or greater does support the USB programming cable with ispPAC-POWR or ispClock devices. When using ispVM System and the USB cable with the Power Manager I devices, (POWR604, POWR1208, POWR1208P1), you must slow down the TCK frequency. This is done using the "Advanced" menus as shown below.
Under the following Menu items: PROJECT>> PROJECT SETTINGS>> ADVANCED>> TCK PULSE WIDTH>> Set this to 2.
This slows down the TCK clock to meet the timing of the ispPAC-POWR JTAG parameters.
To get a JEDEC file from PAC-Designer:
- Enter your design sequence
- Compile design (for ispPAC-POWR devices)
- Go to the Schematic window Use the JEDEC button on the tool bar or go to FILE>EXPORT>JEDEC
Now proceed using the normal ispVM System flow.
