We have recently obtained our Data I/O logic programmer for PALs and other logic devices. One of the main problems we had was in loading the test vectors obtained from the Function test portion of PALASM. Every time we ran PALASM on the VAX and then downloaded to the Data I/O a verification error resulted. The version of PALASM we used was 1.6A. Subsequently we decided to use someone else's copy of version 1.6A and this worked fine! After careful checking we found out that there are two versions of PALASM 1.6A. How frustrating!!! If anyone out there is having a similar problem you might check the JEDEC format of your PALASM code output. All unused and grounded inputs should have X's in their location. The erroneous PALASM we had put L's there instead and the Data I/O did not like these. We are now operating with no problems and are awaiting version 2.0 where all these errors should be fixed. Has anyone out there had any experience with CUPL or ABLE?
