The ispLSI 2096VL is a High Density Programmable Logic Device containing 96 Registers, six Dedicated Input pins, three Dedicated Clock Input pins, two dedicated Global OE input pins and a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements. The ispLSI 2096VL features in-system programmability through the Boundary Scan Test Access Port (TAP) and is 100% IEEE 1149.1 Boundary Scan Testable. The ispLSI 2096VL offers nonvolatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems. The basic unit of logic on the ispLSI 2096VL device is the Generic Logic Block (GLB). The GLBs are labeled A0, A1 .. C7 (see Figure 1). There are a total of 24 GLBs in the ispLSI 2096VL device. Each GLB is made up of four macrocells. Each GLB has 18 inputs, a programmable AND/OR/Exclusive OR array, and four outputs which can be configured to be either combinatorial or registered. Inputs to the GLB come from the GRP and dedicated inputs. All of the GLB outputs are brought back into the GRP so that they can be connected to the inputs of any GLB on the device.
